Which of the following is a consequence of eutrophication in water bodies?

Correct Answer: Algal blooms and decreased oxygen levels

Step 1: Understand what eutrophication is. It is the process where water bodies receive excess nutrients, mainly nitrogen and phosphorus.
Step 2: Recognize that these nutrients come from sources like fertilizers, sewage, and runoff.
Step 3: Know that the increased nutrients cause rapid growth of algae, known as algal blooms.
Step 4: Realize that when algae die, they decompose, which uses up oxygen in the water.
Step 5: Understand that lower oxygen levels can harm or kill fish and other aquatic life, leading to a decline in biodiversity.
