Question

Biomagnification means

• A. Accumulation of pesticide through food chain
• B. Accumulation of pesticide in water
• C. Increased pesticide degradation
• D. Decrease pesticide degradation

Answer 1

The correct option is A Accumulation of pesticide through food chain

Biomagnification refers to increase in concentration of the toxicant at successive trophic levels. This happens because a toxic substance accumulated by an organism cannot be metabolised or excreted, and is thus passed on to the next higher trophic level. Thus, the correct answer is option A.
