Question

Quizplus · Accepted Answer

Acid rain is not a chief contributor of excess nutrients to water bodies. It can contribute to the acidity of the water, which may exacerbate eutrophication, but it is not a nutrient source. Nutrients such as nitrogen and phosphorus from sources like agricultural runoff, wastewater, and fertilizers are the main contributors to eutrophication.
