Text Solution

Verified by Experts

The correct Answer is:
B
DDT is a toxic substance which gets concentrated subsequently in a food chain of an aquatic ecosystem in the following manner
`underset("(0.04 ppm)")("Phytoplanktons") rarr underset("(0.5 ppm)")("Eel")rarr underset("(2 ppm)")("Crab")rarr underset("(25 ppm)")("Seagull")`
Thus, the animal or organism acquiring the highest positron in a food chain would have the highest DDT concentration (here seagull). This process is known as biological magnification or biomagnification.
