Question

A local watershed carries runoff from farms, suburban lawns, and wastewater treatment plants into local rivers, and eventually into a local bay. How could this affect the health of the bay?
A. It could make water hypoxic for organisms.
B. There will be an increase of aquatic plants and fish.
C. It could increase dissolved oxygen for fish.
D. There will be decreased nutrients in the water.

Answer 1

Answer:

answer should be "making water hypoxic for organisms". reason is because the runoff from these treatment plants are filled with nutrients, which will cause eutrophication. eutrophication is excessive algae sprouts which create more DO but then later becomes all used up when they decompose, making it so other organisms have no oxygen.
