A. clogging narrow streams and preventing water from flowing properly.


B. increasing the amount of nutrients available to fish in lakes and streams.


C. causing rapid algal growth that decrease oxygen levels and choke aquatic life.


D. raising the water level in nearby rivers to levels leading to flooding.

Answer 1

C: Causing rapid algal growth that decreases oxygen levels and chokes aquatic life.

If this is incorrect, please, don't refrain to tell me. Thank you.

Answer 2

When fertilizers enter the water surface they cause brisk algal growth, which reduces the levels of oxygen and choke aquatic life.

What is eutrophication?

It is the phenomenon by which the entire water body, or some part of it becomes enriched with nutrients and minerals, mainly the phosphorus and nitrogen. This generally takes place when the fertilizers used in fields get washed in the water body.

A common effect of eutrophication is algal blooms. The emergence of algal blooms results in the depletion of oxygen of the water body resulting in  the choking of aquatic life.

Thus, the correct answer is option C.
