Vedclass · Answer

(C) Eutrophication is a natural process that literally means 'well-nourished' or 'enriched'.It is a natural state in many lakes and ponds that have a rich supply of nutrients.Eutrophication becomes excessive when abnormally high amounts of nutrients from sewage,fertilizers,animal waste,and detergents enter streams and lakes,causing excessive growth or blooms of microorganisms.With increasing eutrophication,the diversity of the phytoplankton community of a lake decreases,not increases,because the lake eventually becomes dominated by a few species of blue-green algae,leading to a loss of overall biodiversity.

Assertion: Eutrophication shows an increase in productivity in water.
Reason: With increasing eutrophication,the diversity of the phytoplankton increases.
