Eutrophication is the presence of too many nutrients in a water body that pollute it and encourage overgrowth of algae and aquatic plants.
Explanation:
Eutrophication is a process whereby too much of nutrients, generally nitrogen and phosphorus, enter a water body (stream, river, or lake) causing algal blooms and growth of aquatic plants which then compete for sunlight, oxygen and space.
Most often this is caused by runoff from land because of the use of nitrogenous and phosphatic fertilisers that leach into the soil and from there enter the water bodies.
Eutrophication, hence, is generally a sign of pollution.
