Question

Non-degradable and fat-soluble pollutant, such as DDT enters the food chain, the pollutant:

• A. magnifies in concentration at each trophic level
• B. degrades at first trophic level
• C. accumulates in the body fat of organism at the first trophic level and does not pass to second trophic level
• D. decreases in concentration at each trophic level

Answer 1

The correct option is A magnifies in concentration at each trophic level

Biomagnification is the accumulation or increasing concentration of lipophilic pesticides in the top members of the food chain.

During biomagnification, the concentration of non-degradable pesticide like DDT goes on increasing along the food chain and highest values occur in the consumers of the top trophic level. So, the value of pesticide will go on increasing at each trophic level.

Thus, the correct answer is option A.
