Question

Eutrophication leads to depletion of dissolved oxygen in water bodies resulting in loss of all aquatic life.

• A. True
• B. False

Answer 1

The correct option is A True

1. Eutrophication: It is the enrichment of an ecosystem with chemical nutrients, typically compounds containing nitrogen, phosphorus or both.
2. The oversupply of nutrients leads to overgrowth of plants and algae.
3. After the death of such organisms, the bacterial degradation of their biomass consumes the oxygen in the water, thereby creating the state of hypoxia (deficiency in the amount of oxygen reaching tissue) that leads to the death of aquatic plants and animals.

The given statement is true.
