Question

_____ is the process of reduction of dissolved oxygen due to the excess growth of algae because of the prasence of lot of nitrogen by the action fertilizers and sewage in pollute water​

Answer 1

Answer:

Eutrophication most commonly arises from the oversupply of nutrients, most commonly as nitrogen or phosphorus, which leads to overgrowth of plants and algae in aquatic ecosystems. After such organisms die, bacterial degradation of their biomass results in oxygen consumption, thereby creating the state of hypoxia.
