Question

is the artificial enrichment of an aquatic system by the addition of nutrients.

• A. Water pollution
• B. Eutrophication
• C. Biomagnification

Answer 1

The correct option is B Eutrophication

The phenomenon of a sudden increase in the organic and inorganic nutrient supply in an aquatic environment is referred to as eutrophication. These nutrients are basically nitrogen and phosphorous, and they favor overgrowth of algae and bacteria, which then results in oxygen depletion in the water.
