Answer 1

Answer:

Eutrophication (from Greek eutrophos, "well-nourished"),[1] dystrophication or hypertrophication, is when a body of water becomes overly enriched with minerals and nutrients which induce excessive growth of algae.[2] This process may result in oxygen depletion of the water body after the bacterial degradation of the algae.[3] One example is an "algal bloom" or great increase of phytoplankton in a pond, lake, river or coastal zone as a response to increased levels of nutrients. Eutrophication is often induced by the discharge of nitrate or phosphate-containing detergents, fertilizers, or sewage into an aquatic system.
