Question

The soil pollutants that affect the food chain and food web by killing microorganisms and plants are

• A. Nitrogen oxides
• B. Pathogens
• C. Pesticides
• D. Agricultural wastes

Answer 1

The correct option is C Pesticides

Pesticides are the chemical compounds which are used for the elimination of the harmful pests and insects. When the pesticides are used in excess, it results in the degradation of the soil and water quality. These are non-biodegradable compounds which enter the food chain and the concentration increases with the increase in the trophic level. The pesticides accumulation in the tissues causes toxicity in the organisms and leads to death.

Thus, the correct answer is option C.
