Match each environmental change with its description. (letters and numbers) (a) biomagnification (b) acid rain (c) eutrophication (1) chemicals react with water and oxygen that enter water system (2) nutrients in excessive amounts enter water systems causing algal bloom (3) a high concentration of toxic chemicals is present in the bodies of animals at the highest trophic levels

The correct answer is -

(A) Biomagnification- option (3),

(B) acid rain - Option (1),

(C) eutrophication - Option (2)

Explanation-

Bio-magnification can be describes as the accumulation of toxic chemical compounds in the body of living organisms that lie at higher trophic levels within a food chain.When chemical compounds like Nitric oxide and sulphur dioxide react with water and oxygen, they form harmful acids that come along with rain, resulting in Acid rain.Eutrophication is a process of accumulation of nutrients ( such as nitrogen and phosphorous) within water body that stimulates the growth of aquatic life forms such as algae, phytoplanktons. This results in formation of algal blooms.

 The answers in the attached file are correct.
