Chesapeake bay is an area that has suffered from overharvesting and eutrophication. Eutrophication is an enrichment of water by nutrients salts that causes structural changes in the ecosystem such as increased formation of algae and aquatic plants, depletion of fish species among other effects. The greatest source of nitrogen and phosphorus in a Chesapeake bay is agriculture

Question 10: True Question 11: Competition and Variation
Explanation:
Natural Selection is when the animal with the best survival rates gets the right to mate. Every species wants to survive and by letting the animals with the best traits reproduce, it ensures their survival. This, of course, happens naturally.
Competition is to show whose fit and whose not and variation increases the chance of their survival. For example, if a whole species was exactly the same if one died of a disease then all of them would, because they would have the same immune system. But if there is variation, one might be vulnerable to the disease but the other might have protection from it. Meaning it could pass those genes to offspring because it was fit.
