Question

When fertilisers are washed into water bodies like lakes and ponds, aquatic plant grow very fast and fill the water body. why do you think this happen what could be the effect on the water body

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.
