Question

A possible consequence of eutrophication is A. Reduction of nutrient levels in a body of water B. Fish kills, because of the lowered dissolved oxygen in the water C. An increase in the biodiversity of the body of water D. Sequestration of dissolved toxins in lake sediments

Answer 1

Answer:

B. Fish kills, because of the lowered dissolved oxygen in the water

Explanation:

Eutrophication refers to the algal bloom as caused by increased levels of nutrients in water bodies. The algal population uses the dissolved oxygen and makes it unavailable or scarce for animals such as fishes present in the water bodies. The scarcity of oxygen leads to the death of fishes in a eutrophic water body.
