ReplyDeleteThis week we learned what is an Estuary. An estuary is very unique. It's when two bodies of water connect. Im a Estuary their is transition which is where tides shift from high and low.These tides are being pulled by the moon gravity. Bracklish is the bond between fresh and salt water which is the two bodies of water that connct in a Estuary. I find this intresting and this to me it's what makes an Estuary cool. I wuld saydifferent animals adapt and learn to live there, even if it's a mixture among types of water and types of creatures. We also learned about Ph, Dissolved oxygen , Temperture and Salinity and coductivity. We tested how these Aboctic d=factors can effect a Boctic creatures that live in a Estuary. We had fake water data based on these four Aboctic factors to go against our given creatures and their real life surival guide. We had to choose if the gievn creatures fit to live in that area and the reason behide why or why not. That was my favorite part because I learned how both factors can effect each others living conditions.
This past two days we learned what is an Estuary is. Estuaries are moderately enclosed bodies of water along coastlines where fresh water and salt water gathers together which they meet. Estuary is mix with fresh water and salt water to be a true estuary. We learned alot this past two days about estuary and how estuary is important. Estuaries are important for the health of the sea in many ways. The estuary is very important for the environment because without estuary fish cant live or reproduce. This is important because if there is no estuary fish can die because the estuary protect the environment where the fish live. Many species, like birds depend on estuaries for food and nesting areas and that shows that without estuary many species could die like bird,fish and other species. We found this interesting because we know that without estuary many species could die because they depends on it. We tested how abiotic factor can affect the biotic species that live in a estuary in many ways and how they survive. Estuaries are important for the health of the sea because without estuary there's nothing for species to reproduce. This shows that many species depends on the estuary in many ways such as fish,salmon,oyster and many species more. This connect to the world in many ways because we have species that live in estuaries and they depend on estuary because estuary protect their environment in many ways.

This week in class I learned about estuary and 4 different abiotic factors. A estuary is a enclosed body of water that has 2 different bodies of water mixed salt and fresh water. When learning about estuary what I found interesting was the different organisms that live in estuary's.The reason I found the organisms that lived in estuary's most interesting was because of the different living condition's each organism had. Which was the limits of tolerance. For example the oysters were able to survive in the estuary because the abiotic factors of the estuary meet with the environmental life of the oysters. The abiotic factors are pH,temperature,salinity/conductivity and dissolved oxygen.This connects to human beings because human beings also have environmental factors that if they weren't to live in them they would probably die.Meaning that if human beings didn't have air they would die and if humans would have to live in water they would die also.Organisms and human beings have different type of living but also share some what the same time of environment in order to survive.

ReplyDeleteThis week we learned about estuaries. Estuaries are we saltwater and freshwater connect, this can also be known as a brackish. Water and saltwater meet at a transition zone. Estuaries are partially enclose bodies of water. We also learned about abiotic and biotic factors. Abiotics factors are factors that happen physically in the environment. Biotic factors are factors that deal with organism and other organisms and how they deal with each other. I think as estuary is very unique because of the changing of tides due to moons gravity. When the changing of tides occurs the animals have to swim to another place because they can die. Also, I think an estuary can be good or bad for some animals because not all animals can survive in a salty water. We also learned about temperature, dissolved oxygen , pH , and Salinity and how they affect the estuaries. Estuaries can be used for fishing , swimming , and just to enjoy the nature. I believe that by us building Skyscrapers and polluting water near estuaries we are creating it to be unsustainable. Estuaries in NYC can be known bays, harbors and sounds. I believe that since estuaries are very unique we should take of them and not pollute the water.

ReplyDeleteThis week we learned what an estuary is. An estuary basically is the core in which fresh water and salt water meet. Estuaries also contain many animals for example shrimp, crabs, clams, oysters, snails, worms, and fish. We also learned about four a biotic factors. One factor was ph, which is an indicator of whether water is acidic or basic. Another a biotic factor was temperature which is a measure of kinetic energy or energy of motion. Another factor was dissolved oxygen is the amount of oxygen gas that is dissolved in a sample of water. And the last factor was salinity, which is the measure of the dissolved salts in water. I found this topic the most interesting so far this year because the measure of these four factors determined how animal life in water would get affected. For example if an oyster lived in a body of water that had salinity below 5 ppt or above 25 ppt that oyster would not survive to long. This can be related to how humans live also. For example if it’s too cold humans may get sick and if it’s too hot people who have allergies will have worse allergy symptoms. So basically the environment can affect you in certain ways.
ReplyDeleteThis week we learned about estuaries which is mainly were saltwater and freshwater meet also known as brackish water.Estuaries are also partially enclosed bodyof water where two different bodies of water meet and mix.This week we also learned that estuaries are transition zones.Some feature of estuaries are swamps,lagoons,bays and harbors some wildlife that you may be able to find in estuaries are blue crabs oysters alewife clams and coho salmon.Abiotic factors happen directly to the environment since abiotic means not alive biotic factors which mean alive deal with the organisms.Estuaries should be kept clean and unpolluted just for example the Bronx River which is polluted and was once a place where fishes and people used to swim in it but now that water is filled with garbage and just plain junk which people are trying to et rid of and restore the bronx rive to it’s previous form and allow animals come back to it’s natural habitat.

ReplyDeleteThis week I learned that we have estuaries here in New York. This came across as a little surprising to me because for some reason, I always thought that estuaries only existed in rare parts of the United States. I am so accustomed to only hearing about the urban life that surrounds us, therefore it is a little weird hearing about preserving an ecosystem in New York city. I also learned that if an organism wants to survive in an estuary, they must be able to adapt to the changing Abiotic factors of the environment, such as temperatures, salinity, weather, and being able to survive on land. This seems like a microcosm of an individual living in New York City because of the extreme climates that occur throughout the years, such as heat waves, thunderstorms, snowstorms, temperatures below zero, or over a hundred degrees Fahrenheit. This example teaches how adaptable these organisms must be in order to survive in an estuary, especially in New York City. Biotic factors may also contribute to the well being of these organisms in estuaries because the organism may or may or not have a predator or the organism's prey may or may not be there.
Learning about estuaries was interesting. An estuary is unique because it is where salt and fresh water mix. This process helps to create a different type of habitat. Organisms such as oysters, mussels, blue crabs, and diamondback turtles have adapted to this brackish environment. Abiotic factors are essential in determining whether or not an environment is habitable. This not only affects native species but us as well. The pH levels found in water is one abiotic factor that affects us because we drink water. If the acidity of water is too high or too low then it can be harmful to us. A community affected by this would be catastrophic and cause illness to spread. Salinity is another abotic factor that can harm us and other organisms. The effects of salinity would be similar to those of high or low pH levels. Dissolved oxygen and temperature are conditions that do not affect us directly. Dissolved oxygen and temperature have a greater impact on the organisms that live in the estuary. Dissolved oxygen and temperature along with tide levels can limit the number of species in an estuary and the limit can also affect spawning. The limitation can affect an ecosystem because predators would have a limited amount of food to eat. Although we learned about abiotic factors such as pH level, temperature, salinity, and dissolved oxygen there are still other abiotic factors such as nitrate, phosphate, and turbidity that affect an environment. Abiotic and biotic factors both play a role in shaping an environment and ecosystem.
ReplyDeleteAn estuary is an enclosed coastal body of water and salt mixed together , depending on the fracture through the worlds system we would be most likely to develop a natural resource in all of man kind. Our society isn't just an ordinary society , its based on a society of immense natural habitats. Estuaries come in various forms like shallow open waters, freshwater and salt marshes, swamps, sandy beaches, mud and sand flats, rocky shores, oyster reefs, mangrove forests, river deltas, tidal pools, etc. Living organisms surround estuaries and in order for them to survive they need the formation balanced out thoroughly. Birds, mammals, fish, and other wildlife depend on estuary habitats as places to live, reproduce, and feed. Also we have estuaries formed by glaciers. It is important to keep estuaries protected as much as possible to keep our cycle running clean and safe. When i think of estuaries i think of keeping my family together, the way we resolve our problems is compared to solving the natural habitats and resources of the estuaries, the way the family is united and kept stabilized is the way i picture the living organisms that live among these estuaries, although developed critically its suppose to be typically organized in a fortunate matter.
ReplyDeleteThis week I learned about an estuary and its 4 a biotic factors.An estuary is fresh water combined with salt water.This is also called brackish water.In an estuary the water level can be high or low depending on the day.Some animals that can live in estuaries are blue crabs,mussels,salmon,oysters and many more.The 4 a biotic factors are temperature,pH,salinity,and dissolved oxygen.Temperature is a measure of kinetic energy or energy of motion.Water temperature is greatest at 4 degrees Celsius.Water at higher or lower temperatures will float.PH is a measure of the amount of hydrogen ions in a solution.Numbers below 7 are acidic and above 7 are basic.Salinity is how salty the water is.Dissolved oxygen is the amount of oxygen in the water.The lower the temperature the more oxygen water can hold. The higher the temperature the less oxygen water can hold.If there is not enough oxygen there can be a dead zone.These factors determine if the animals can live in an estuary or not.Estuaries can be a habitat for many animals.That is why we have to make sure that the water is clean and that people take care of the environment.
ReplyDeleteEstuary was a word that I kept hearing but never knew what it really meant. But once I learned what it really meant, it just became a new word for my dictionary. Also when I saw how an estuary looks like, I just asked myself why isn’t this seen everyday? Simply an estuary is when salt water and fresh water meets, and once they meet it becomes an incredible river that can include many different species. Since this is a new type of water well known it creates a new habitat for new creatures like the oysters, blue crabs, and diamondback turtles. Estuary makes these species to change to different water. The water has a specific characteristic that gives a color to the species. With this main topic of estuary we learned about 4 different types of abiotic factors. There were few abiotic factors that were tried out. The pH started out with filling in a bottle and inserting 2 capsules in the bottle. We had to wait for the capsules to dissolve and took over 10 minutes till it finally made a color change. With that color change we could see and compare to the pH chart and see what’s its level. We have figured out that the level was 7 and that means it’s safe water. If the color was different and was closer to either 1 or 14 then it might mean the water was more acid like and wont be good for the environment. Estuary it’s just a great part for nature and the community should be concern with this. If the state actually cared more with this, it could attracted more people and would make the city well known not only with its skyscrapers but as well its estuaries.
ReplyDeleteAn estuary is where freshwater and salt water mix and meet, this can also be known as brackish waters. There are four abiotic factors that determine what kind of animals can live in the water. PH helps determine if the water is acidic or basic. If the pH level is less than 7 degrees celsius then the water is acidic, if the pH level is more then 7 degrees celsius then the water is basic. Most animals cannot live in waters where the pH is below 5 or above 9 degrees celsius. Salinity and conductivity measures the dissolved salts in water. Salinity affects the ability of water to hold oxygen while conductivity measures the ability of water to conduct currents. Salinity and conductivity depend on rain, evaporation and geology. Temperature is a measure of energy, the higher the water temperature the more energy that is being used. Temperature is very important because if the water gets too hot the animals will die and if the water gets too cold the fish will freeze to death. To survive aquatic life must have a good level of dissolved oxygen. The ability of the oxygen dissolving in water decreases as the waters temperature and salinity increases. I never thought that one body of water would have so many things going on under the surface. Above the water it just looks like water that is constantly moving, but below the surface there is a lot of things going on. I was always told not to judge a book by it's cover but I didn't think that it would also apply to water.

Estuary is the place that the combination between salt water and fresh water mix. This liquid combination is named brackish water, which is the same concept of it being salt water and fresh water. This new combination of water helps create salt marches, which are essentially a costal of grassland that is covered by this brackish water, this new environment is a habitat where many organisms may thrive or just survive. These animals are kept alive depending on the abiotic factors (non-living chemical and physical factors in the environment), these also help determine if the environment is facing problems. Factors such as the pH levels can help keep either a species of organism alive or dead because certain species of aquatic animal require standard pH levels to survive; the acidity of the water. Such an example is the alewife fish, which needs an estimate of 4-9 pH level to survive; if lower or greater than indicated then the fish would die. Furthermore a factor that also helps an aquatic animal to survive is temperature, which is the kinetic energy used to heat things up. The change in temperature can destroy the habitat of animals as they need a certain amount of temperature to spawn and thrive. Another abiotic factor is the dissolved oxygen, which is the amount of oxygen put in the water for fish and other sea creatures to survive. Same with humans, fish need oxygen to survive. Finally another factor is the salinity of the water, which is how salty is the water.
ReplyDeleteThese ideas connect as to how sustainable this estuary is for other animals. Also it shows how animals need a specific area and suitable environment to live in. Overall these sudden alterations of the estuary can mean the extinction of many animals, thus disruption the food chain. In order to prevent this we as a community of people should make less types of pollutants and throw absolutely no waste in order to prevent the extinction of aquatic animals.
Estuaries are where fresh water, from rivers and stream, and salt water, from the ocean, meet and mix, can also be known as brackish water. Estuaries are dependent on tides and are often bodies of water also called swamps, lagoons, bays, harbors, sounds and bayous. Animals such as oysters, blue crabs, mussels, cord grass, eel grass, diamond back terrapins, killifish, ale wires, blue herons, and coho salmons are some of the organisms that inhabit estuaries.
ReplyDeleteTo test an estuary, there are four abiotic factors that test the water’s quality: temperature, dissolved oxygen, pH, and salinity. Temperature is the measure of kinetic energy, dissolved oxygen is the amount of oxygen gas that is dissolved in a sample of water, salinity is the measure of the dissolved salts in water and pH is the measure of the amount of hydrogen ions in a solution. These factors are important to test because it helps to determine if the water is in good condition for its inhabitants. According to the readings we read today, I was surprised to learn that the river is slowly being restored into good condition. I used to think the river is polluted and it just co-exists with the rest of our community.
This week in environmental science class we learned about what an Estuary is.How is it different and what makes it unique. An estuary is when two of water connect and mix. When the mix happens the water turns brackish. Brackish water is a combination of salty water and fresh water. This kind of water is only found in Estuaries because thats where the connection happens. Estuaries are very interesting places because not any animal or plant could manage to live there. Not all of them have what it takes to live in an environment where a mixture of water happens.Also this week we learned about Ph, Dissolved oxygen , Temperature and Salinity and conductivity. We learned about this because we were trying to see what kind of animals could live in a certain type of water with a different ph level , D.O, temperature and S.A. believe it or not the lives of a lot of animals depend on these factors. I found this lesson so interesting because it answers a lot of my questions. I used to ask myself why can't this type of fish live in this type of water ?. Now I know that factors of a water are very important.Also before I used to think that all water was the same. now I see that all types of water are different and thats why there is different fishes and plants in different bodies of water.
