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

Inorganic fertilizers containing phosphates and nitrates released into water bodies give out a lot of nutrition to phytoplankton. It causes eutrophication. Algal growth occurs tremendously. Decomposition of these algae makes the aerobic decomposers highly active which in turn causes depletion of dissolved oxygen in water bodies. Lack of dissolved oxygen in water leads to death of aquatic animals, especially fishes, due to suffocation.
