Which of the following exhibits biomagnification?
a. SO2
b. Mercury
c. DDT
d. Both b & c
Answers (1)
Explanation: The term "biomagnification" describes the rise in toxicant concentration at successive trophic levels. This occurs when an organism accumulates harmful substances that are unable to be metabolised or eliminated, causing them to be transferred to the next higher trophic level. This is a well-known phenomenon for DDT and mercury. Hence, (d) is the correct option.
