Main cause of eutrophication is
fluctuation of temperature
unusual growth of aquatic vegetations
enrichment of nutrients
abundance of microorganisms
C.
enrichment of nutrients
Eutrophication is the natural aging of lakes whose process starts due to heavy discharge of pollutants. Normally in young like, water is clear and support healthy healthy life, with time due to the enrichment of nutrients such as nitrates and phosphates mainly the industry, sewage, agricultural waste, also waste from home, etc., enters the lakes hinders the aquatic system. This occurs because of overstimulation of growth of algae or algal bloom.
