Question

Pesticides sprayed in the environment can threaten predators in the area, this can cause

• A. Global warming
• B. Eutrophication of lakes
• C. Depletion of the ozone layer
• D. Magnification in the food chain
• E. Acid rain

Answer 1

The correct option is D Magnification in the food chain

Global warming is caused by increased concentration of greenhouse gases in the atmosphere. Increased organic matter in lakes causes eutrophication. Ozone depletion is mainly related to the use of CFC-based products. Acid rain is the result of increased sulphur and nitrogen oxide levels in the atmosphere. Increased use of pesticides causing the death of predators will cause accumulation of nonbiodegradable compounds like DDT in the food chain. Thus, the correct answer is option D.
