Question

17-What is Eutrophication? Write its process.

Answer 1

Eutrophication (from Greek eutrophos , "well-nourished"), [1] or hypertrophication, is when a body of water becomes overly enriched with minerals and nutrients that induce excessive growth of plants and algae. [2] This process may result in oxygen depletion of the water body. [3] 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.
