Question

Explain the process of Eutrophication

Answer 1

Answer:

Eutrophication is the process in which lakes receive nutrients (phosphorus and nitrogen) and sediment from the surrounding watershed and become more fertile and shallow. The additional nutrients are food for algae and fish, so the more eutrophic a lake is, the more living organisms it sustains.

Human activities can contribute excess amounts of nitrogen and phosphorus into water. Therefore, human causes of eutrophication include the use of agricultural fertilizers. Other causes include sewage and aquaculture, which is the growing or farming of fish, shellfish and aquatic plants.
