Some toxic compounds are ingested and retained in the tissues. these pollutants pose special risks to humans and other organisms high on the food chain because of which process?
a) carcinogenesis
b) compound contamination
c) biomagnification
d) synergism
e) threshold effect

Option C, Bio magnification

Explanation:

In a food chain or energy pyramid, the amount of energy transferred at each succeeding trophic level reduces as compared to the previous trophic level. However, in case of toxic chemicals this flow of energy or food reverses and the amount of toxic chemical increases at each succeeding trophic level as compared to the previous trophic level. This mechanism of accumulation of toxic chemicals at higher trophic levels is known as bio magnification.

Hence, option C is correct

it will be bbb bbb bbb bbb bbb bbb bbb bbb
