Nitrogen pollution has become a major problem around the world.

2. How does the amount of fertilizerused by farmers affect the surrounding water for shrimp catchers? • Nitrogen pollution has become a major problem around the world. • Some sources of nitrogen pollution include car exhausts, power plants, and agricultural fertilizers which all lead to acid rain, groundwater contamination, and over-enriching of marine habitats with nutrients. • Many types of algae and plankton, and other organisms at the bottom of the food chain, react to over-enroiching by blooming, or increasing the population size. • On average, the shrimp grow to be 8 to10 millimeters long. • The results of this experiment show that an excess of nitrogen fertilizer introduced into the water of brine shrimp affects the population number.

3. More Info • The growth and survival of organisms depend on the physical conditions. • Brine shrimp can survive in seawater and brackish water and can be found in salt lakes and brine ponds all over the world. • Brine shrimp have no defense against predation • They can best thrive in conditions in which their predators cannot, such as high salinity and temperature. • Newly hatched brine shrimp can be grown to full maturity in about three weeks • The brine shrimps' development at regular intervals.

4. Even More Info • the fertilizer seeps through the soil into the water table. This can eventually lead to the contamination of a local water source, like a stream, pond, lake, bay, or ocean. • agricultural practices that frequently use large amounts of fertilizer on fields that are connected by Irrigation channels • The run-off of fertilizer seeps into the irrigation channels and eventually joins with a river or other body of water. • You can do an experiment with sod in a tray to measure the amount of fertilizer run-off. Apply different concentrations of fertilizer in water to sod in a plastic tray. After allowing the sod to soak in the solution, tip the try over a bucket to collect the run-off. • You can test for the concentration of nitrogen in the run-off as a test for how much fertilizer collected as run-off.

5. All that stuff in my own words • Nitrogen pollution a big problem. • Some things that are nitrogen pollution are car exhausts, power plants, and garden fertilizers which all lead to acid rain, groundwater contamination, and over-enriching of marine habitats with nutrients. • Many types of algae and plankton, and other organisms at the bottom of the food chain, react to over-enroiching by blooming, or have bigger population. • On average, the shrimp grows to be huge! • The results of this experiment show that an excess of nitrogen fertilizer introduced into the water of brine shrimp affects the population number.

6. More In My Own Words • The growth and survival of marine life depend on the conditions. • Brine shrimp can survive in different kinds of water and can also be found in salt lakes and brine ponds all over the world. • Brine shrimp have no defense against enemies. • They can best thrive in conditions in which their enemies can't, such as high salinity and temperature. • Newly hatched brine shrimp can be grown to full maturity in about three weeks • The brine shrimps' development at regular intervals.

7. In My Words • the fertilizer goes though the soil into the water table. This can eventually lead to the contamination of a local water source. • farmers that frequently use large amounts of fertilizer on fields that are connected by Irrigation channels • The run-off of fertilizer goes into the irrigation channels and goes into with a river or other body of water. • You can do an experiment with dirt in a tray to measure the amount of fertilizer run-off. Apply different concentrations of fertilizer in water to the dirt in a plastic tray. After allowing the dirt to soak in the fertilizer, tip the try over a bucket to collect the run-off. • You can test for the concentration of nitrogen in the run-off as a test for how much fertilizer you got off run-off.

8. How does the dead zone form, and how are animals affected? • The dead zone forms starting off with freshwater that comes from the Mississippi river floats of top of the salty gulf of Mexico water. Fertilizer in the freshwater layer and make huge algae blooms. Next when the algae blooms die they sink to the bottom. Later they need oxygen so the animals die or swim out of the area. Then it becomes a dead zone. Chemicals can also get into the dead zone and make the dead zone. O.M

9. How do the animals get affected because of the dead zone? • The animals can get affected by the dead zone because when the chemicals and fertilizer get into the dead zone they can get down to the bottom of the water and spread. As soon as it spreads it gets to the animals. When it gets to the animals, the animals eat the chemicals and then they die. Also algae can affect them, when the algae is on top of the water and it dies, it then sinks to the bottom bacteria sucks up the algae pulling large amounts of oxygen. O.M

10. How Does The Fishermen Get Affected Because Of The Dead Zone? • The fishermen can get affected because of the chemicals. When the chemicals get down to the dead zone where the animals are the animals drink the chemicals and then the animals die, which leaves the fishermen with no food. Also they can get affected because of the fish, when the fish swim out of the area to avoid the dead zone there are no fish in the area, so fishermen can’t fish for food. O.M

11. How Does The Chemicals And Fertilizer Get Into The Dead Zone? • Chemicals and fertilizer can get into the dead zone by fertilizer and chemicals that are sprayed on plants end up washed into rivers, lakes, and streams from farm fields, feed lots, yards, and city streets. Then the chemicals and fertilizer that are in the lakes and streams get washed into the Mississippi River. After that, they move into the waters of The Gulf Of Mexico. O.M

12. Did You Know 1st Question How does the fertilizer and all the bad chemicals get in the dead zone? • chemicals can get into the dead zone because it is from the farms and all the other places, then it gets to the rivers and streams ,and after that is goes to the Mississippi river, finally it flows to the dead zone. • fertilizer can get into the dead zone if farmers use too much fertilizer then the fertilizer will get into the streams if there is fertilizer left over, after that the fertilizer gets into the lakes and streams, and then it goes to the Mississippi river, and finally it gets to the dead zone. • fertilizer and chemicals can also get into the dead zone if it is from factories or a place that has a lot of workers and produces a lot of products each day, and then it goes to rivers ,and then leads to the dead zone. O.M

13. Did You Know 2nd Question How do the animals get affected because of the dead zone? • Sea creatures can get affected because when the fertilizer and bad chemicals get into the dead zone, it sinks to the bottom where the sea creatures are and then the sea creatures die and that affects them. • also animals can get affected because of the algae, when the algae gets on top of the water it dies, then it sinks to the bottom where bacteria sucks up the algae, pulling large amounts of oxygen out of the water in the process. • Lastly the animals/sea creatures can get affected because if they can escape from the fertilizer once it gets down then if they swim out of it there will be more fertilizer and then they will be trapped in the dead zone and then they will die. O.M

14. Did You Know 3rd Question How Does The Fishermen Get Affected Because Of The Dead Zone? • Fishermen can get affected because of fertilizer and chemicals when they get down to the dead zone, the fish eat it and then the fish die. So that leaves the fishermen with no fish. • Also fishermen can get affected by the fish because, if the fish swim out of the area avoiding the chemicals then there will be no fish. Also if the fish eat the chemicals than they die and that also affects the fishermen. • Lastly, fishermen can get affected because of the algae. When the algae gets on the water and dies it then sinks to the bottom and spreads where the animals are, then, bacteria sucks up the algae pulling large amounts of oxygen. O.M

15. Call To Action • Next time if your are near farm fields, feed lots, yards, and city streets, use less fertilizer or don’t use any fertilizer so that you can save the sea creatures and they won’t die or at least have a chance of living. Also, if you are near a farm and there is a farmer there, tell the farmer to use less fertilizer because farmers use too much fertilizer. If everyone starts doing this then the fish will survive and the fishermen will be able to fish for food. The dead zone might not be called the dead zone anymore. O.M
