Question

Phosphate containing fertilizers cause water pollution. Addition of such compounds in water bodies causes:

• A. Enhanced growth of algae
• B. Increase in the amount of dissolved oxygen in water
• C. Deposition of calcium phosphate
• D. Increase in fish population

Answer 1

The correct option is A Enhanced growth of algae

Phosphate containing fertilizers cause water pollution. Addition of such compounds in water bodies causes enhanced growth of algae and hence, results in a decreased amount of dissolved oxygen in water.
Due to lack of dissolved oxygen, fish population greatly reduces.
