Question

Which one of the following gets biomagnified at different levels in a food chain?

• A. Carbon monoxide
• B. CFC's
• C. DDT
• D. Manure

Hint:

DDT is a persistent chemical that accumulates in the tissues of organisms, leading to harmful effects at higher trophic levels.

Answer 1

The Correct Option is C

Biomagnification refers to the process by which the concentration of certain substances, such as pesticides, increases as you move up trophic levels in a food chain. DDT, a pesticide, is a well-known example of a substance that biomagnifies. As it accumulates in organisms, it becomes more concentrated at higher trophic levels, affecting top predators. Therefore, the correct answer is option (3).
