Question

8. The process through which pollutants get increas-

ingly more concentrated at each step up the food
chain is
a. biomagnification.
b. anaphylaxis.
c. toxicity.
d. bioaccumulation.

Answer 1

Biomagnification is the process through which pollutants become increasingly concentrated as they move up the food chain.

Step-by-step explanation:

The correct answer is option A, biomagnification. Biomagnification is the process through which pollutants become increasingly concentrated as they move up the food chain. This occurs because organisms at higher trophic levels consume a larger quantity of prey organisms that have accumulated pollutants. For example, if a small fish eats zooplankton that have been exposed to a pollutant, and then a larger fish eats many of the smaller fish, the pollutant will become more concentrated in the larger fish. This process can result in high levels of pollutants in top predators, which can have negative effects on their health.
