Question

Nutrient enrichment of a lake will cause

• A. Eutrophication
• B. Stratification
• C. Biomagnification
• D. Bioaccumulation

Answer 1

The correct option is A Eutrophication

Eutrophication is a condition where the excessive richness in the environment leads to overgrowth of the plants in the water bodies which leads to decrease in the oxygen content of the environment as the dissolved oxygen of the water is used up by the organism growing there. It leads to organic loading, depletion of oxygen, death of animals and fouling of water.

So, the correct answer is option A.
