NEET BIOLOGY

Detailed explanation-1: -Nutrient pollution, a form of water pollution, is a primary cause of eutrophication of surface waters, in which excess nutrients, usually nitrogen or phosphorus, stimulate algal and aquatic plant growth. A common visible effect of eutrophication is algal blooms.

Detailed explanation-2: -Based on the root cause of eutrophication, we can classify eutrophication into two types, namely anthropogenic eutrophication and natural eutrophication.

Detailed explanation-3: -Cultural eutrophication occurs when human water pollution speeds up the aging process by introducing sewage, detergents, fertilizers, and other nutrient sources into the ecosystem.

Detailed explanation-4: -Artificial eutrophication is a process that increases the amount of nutrients in a body of water through human activities, such as waste disposal and land drainage. The major causes of eutrophication are fertilizer and phosphates in some laundry detergents.
