Question

Quizplus · Accepted Answer

A foul-smelling lake that is rich in algae and rooted plants but lacks oxygen is referred to as eutrophic. Eutrophication occurs due to excess nutrients, especially nitrogen and phosphorus, which causes an overgrowth of algae and other aquatic plants. As these plants die and decay, bacteria consume oxygen, leading to low dissolved oxygen levels in the water, which can result in a foul smell.
