Question

Eutrophication can be observed in

• A. Saline soil
• B. Desert
• C. Fresh water lakes
• D. Agricultural fields

Answer 1

The correct option is C Fresh water lakes

Part of fertilizers added to crop fields are passed down to water bodies like freshwater lakes located nearby, during rains, through surface runoff. The presence of extra nutrients brings about the dense growth of plant and animal life. The phenomenon is called eutrophication. Eutrophication leads to organic loading, depletion of oxygen, the death of animals and fouling of water.

So, the correct answer is 'Freshwater lakes'.
