Answer:
Algal Blooming
Presence of the fertilizers and sewage in polluted water provides a lot of nitrogen, causing excessive growth of algae which subsequently reduces the amount of dissolved oxygen in water is called "Algal Blooming" ...
Some Important Points :-
• Some algal blooms are the result of an excess of nutrients (particularly phosphorus and nitrogen) into waters and higher concentrations of these nutrients in water cause increased growth of algae and green plants.
• This causes an increase in the biological oxygen demand (BOD), resulting in the death of fishes and other aquatic animal.
