Question

Phenomenon involved in increasing the concentration of non-degradable pollutants in a trophic level of an ecosystem is called

• A. Biodegradation
• B. Biomineralization
• C. Bioaccumulation
• D. Biomagnification

Answer 1

The correct option is D Biomagnification

• Biodegradation is a natural way of recycling wastes. It is a process of breaking down organic matter into nutrients that can be used by other organisms.
• The phenomenon by which bacteria and other organisms produce minerals is called biomineralization.
• The phenomenon of concentrated toxic deposition at a higher trophic level is known as bioaccumulation.
• The phenomenon of increase in the concentration of non-biodegradable pollutants from lower to higher trophic levels is called biomagnification.
• DDT being toxic and interrupting the food chain by accumulation causes biomagnification.

Thus, the correct answer is option D.
