NEET BIOLOGY

Detailed explanation-1: -Nutrient pollution, a form of water pollution, refers to contamination by excessive inputs of nutrients. It is a primary cause of eutrophication of surface waters (lakes, rivers and coastal waters), in which excess nutrients, usually nitrogen or phosphorus, stimulate algal growth.

Detailed explanation-2: -Pollution resulting from the use of fertilizers and the disposal of sewage from humans and livestock can lead to an algal bloom.

Detailed explanation-3: -They are most commonly caused by dinoflagellates or diatoms but can also be caused by cyanobacteria. Blooms can occur in brackish waters in the United States, including estuaries and coastal waters. Blooms in brackish water are most commonly caused by dinoflagellates or diatoms but can also be caused by cyanobacteria.

Detailed explanation-4: -Excess nitrogen and phosphorus cause an overgrowth of algae in a short period of time, also called algae blooms. The overgrowth of algae consumes oxygen and blocks sunlight from underwater plants.

Detailed explanation-5: -Phosphorus and nitrogen are essential to algae production, and these nutrients encourage the growth of algae in waterbodies.
