Quizplus · Accepted Answer

Eutrophication is caused by excessive nutrients, mainly nitrogen and phosphorus, which promote excessive plant growth, leading to water quality degradation and oxygen depletion in water. The use of fertilizers is a major source of these nutrients in water bodies, contributing to eutrophication in Chesapeake Bay, Gulf of Mexico, and other locations. Heavy metals, pesticides, and weather are not significant contributors to eutrophication in these areas, and while global warming may exacerbate the problem, it is not the root cause.
