Question

In a polluted environment, maximum pollution will occur in.

• A. Primary producers
• B. Tertiary consumers
• C. Secondary consumers
• D. Primary consumers

Answer 1

The correct option is B Tertiary consumers

• When biomagnifications affect a food web, the animals on the upper tiers tend to eat and store more pollutants.
• In a polluted environment, biomagnification causes maximum pollution to occur in tertiary consumers which are at the uppermost tier of the food chain..
  
• In the process of biomagnification, toxins or pollutants are concentrated in an organism as larger animals continue to eat smaller animals. This process moves toxins or pollutants up the food chain to larger organisms. For example, a large fish that eats multiple small fishes that ingested a pollution-related chemical will consume large amounts of the toxin.
• So the correct answer is 'Tertiary consumers'.
