Question

Arrange the following organisms in increasing order of biomagnificaion.

• A. Zooplankton
• B. Algae
• C. Small fish
• D. Large fish
• E. Birds

Answer 1

The amount of non-biodegradable toxic substances accumulated within an organism's body increases higher up the food chain, or as we go higher up the trophic levels. The steep increase in the amount of toxic substances in the tertiary consumers as compared to primary consumers is known as biomagnification. Hence,
Algae→Zooplankton→Small fish→Large fish→Birds
