Question

what is utrophication​

Answer 1

excessive richness of nutrients in a lake or other body of water, frequently due to run-off from the land, which causes a dense growth of plant life is eutrophication.

Answer 2

Eutrophication or hypertrophication, is when a body of water becomes overly enriched with minerals and nutrients which induce excessive growth of plants and algae.This process may result in oxygen depletion of the water body.One example is the "bloom" or great increase of phytoplankton in a water body as a response to increased levels of nutrients. Eutrophication is almost always induced by the discharge of nitrate or phosphate-containing detergents, fertilizers, or sewage into an aquatic system.
