Question

Q. Consider the following statements:

Which of the above can help mitigate Algal Bloom?

• A.
  1 and 2 only
• B.
  2 only
• C.
  1 and 3 only
• D.
  1, 2 and 3

Answer 1

The correct option is C

1 and 3 only
Explanation:

Statements 1 and 3 are correct: Algal blooms are the result of an excess of nutrients (particularly phosphorus and nitrogen) into waters and higher concentrations of these nutrients in water cause increased growth of algae and green plants. Digging small lakes and diverting surface runoff will reduce nutrient mixing in the water body mitigating Algal Bloom.

Statement 2 is incorrect: Phosphate based detergents increase Eutrophication resulting in Algal Bloom.
