Name the fertilizers whose excessive presence in water bodies results in algal growth. What is the consequence of eutrophication.

Answer :

Fertilizers like phosphates, phosphorous and nitrogen result in algal growth in water bodies.
Eutrophication is a phenomenon wherein excess of nutrients, chemicals in water body result in algal growth which stops the sunlight from reaching to the aquatic plants due to which plants do not produce oxygen and the aquatic animals die due to lack of it. Thus, eutrophication reduces the oxygen content (biological oxygen demand increases) due to which life forms are affected and they die. Water quality is drastically reduced as the toxicity is increased.
