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

Explanation

Inorgaic fertiliers containing phosphates and nitrates releasesd into water bodies give out a lot of nutrition to phytoplankton. It causes eutrophication. Algal growth occurs tremendously. Decomposition of these algae makes the aerobc 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.
