High concentration of nutrients especially nitrates and phosphates in water can accelerate which of the following phenomenon ?

Options

A. Algal bloom
B. Eutrophication
C. Biomagnification
D. Both (a) and (b)

Answer

D

Explanation

Eutrophication is the excessive growth of algae, plants and animals in water bodies due to the nutrient enrichment particularly with nitrogen and phosphorus. This excessive growth of planktonic algae that causes colouration of water is called algal bloom. So, the high concentration of nitrates and phosphates in water increases both the eutrophication and algal bloom.
