What effect does eutrophication have on aquatic ecosystems? A.
It prevents sunlight from reaching aquatic life below the water’s surface.
B.
It negatively impacts aquatic vegetation but is beneficial for all aquatic animals.
C.
It decreases carbon dioxide concentration, which is harmful for aquatic animals.
D.
It lowers the concentrations of nitrogen and phosphorous available to marine animals.

The answer is C

Explanation:

Eutrophication can have serious effects, like algal blooms that block light from getting into the water and harm the plants and animals that need it. If there's enough overgrowth of algae, it can prevent oxygen from getting into the water, making it hypoxic and creating a dead zone where no organisms can survive.

 I just took the test on Plato and unfortunately the correct answer is NOT C. It decreases carbon dioxide concentration, which is harmful for aquatic animals.
