Question

Rapid growth of algae in water bodies is because of detergent having:
(A) carbonates salts
(B) sulphate salts
(C) phosphate salts
(D) sulphonic acid salts

Answer 1

Answer:B

Explanation:

Answer 2

The rapid growth of algae in water bodies is because of detergent having (C) phosphate salts.

• Algae feed on phosphate salts of detergents and multiply rapidly.
• Algal growth on large scale is seen in water bodies where phosphate-rich waters accumulate. it is due to the water entering the water body from nearby industries and from the field after irrigation where insecticides, pesticides and fertilisers are used. pesticides and fertilisers contain phosphates.
• The accumulation of these phosphate salts causes algal bloom and the surface of the water got covered with algae. thus, preventing the oxygen from being rich inside the water body. algae also consume some part of oxygen.
• Lack of oxygen results in large scale death of fish.
