Please help: What effect does eutrophication have in aquatic ecosystems? A. It prevents sunlight from reaching aquatic life below the waters 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 concentration of nitrogen and phosphorus available to marine animals

The answer is D

Explanation:

an overabundance of nutrients primarily nitrogen and phosphorus which is in the water starts a process called eutrophication which makes it decrease. when the algae dies they are decomposed by bacteria. This process consumes the oxygen dissolved in the water which is needed by fish and other Aquatic Life to breathe.

It isn't C because it actually increases carbon dioxide not lower.

It isnt B because it does negatively impact aquatic vegetation but it is not beneficial for all aquatic animals

A isn't the the correct answer because eutrophication has nothing to do with sunlight into the ocean

So the only answer left which is correct is D

(I hope this helps you! have a wonderful day everyone!)
