Question

Quizplus · Accepted Answer

Eutrophication occurs when there is an excessive amount of nutrients, particularly phosphorus and nitrogen, in the water. Detergents often contain a significant amount of phosphate, and if they were dumped into the lake, it could lead to eutrophication. The other choices do not directly contribute to eutrophication.
