Question

Addition of phosphates and nitrates/fertilizers into water leads to _________

• A. Eutrophication
• B. Increased growth of decomposers
• C. Reduced algae growth
• D. All of the above.

Answer 1

The correct option is A Eutrophication

Addition of phosphates and nitrates/fertilizers into water leads to nutrient enrichment which is also called as eutrophication. It is the process in which nutrient enriched water bodies support a dense plant population, which kills animal life by depriving it of oxygen. It results in the loss of biodiversity. Hence, the correct answer is option (a).
