Correct answer: B. Seagull
- A. Phytoplankton
- B. Seagull
- C. Crab
- D. Eel
Explanation
DDT is non-biodegradable and is not metabolized within the body of an organism; rather it accumulates in the fat tissues therefore its concentration goes on increasing from one trophic level to another of a food chain. The highest amount is present in the top consumer i.e., it shows biomagnification. In an aquatic food chain, the seagull is the top carnivore, therefore, will possess the highest concentration of DDT.
