How can acid rain affect organisms living in lake water?

Answer and explanation

Correct answer: It can lower water pH and disturb life processes

The governing concept is the ecological effect of acid-base change. Acid rain contains acidic oxides and dissolved acids that can lower the pH of lake water. Aquatic organisms function within particular pH ranges; excessive acidity can disturb enzyme activity, respiration, reproduction, and survival. Therefore option A is correct. B reverses the effect, while C and D ignore the biological and chemical consequences of lower pH.
