Question

What happens when phosphorus, nitrates, and detergents in water lead to an acceleration in the growth of algae?

• A. Extinction
• B. Eutrophication
• C. Increase in the number of fishes
• D. Increase in the number of aquatic plants

Answer 1

Answer:

B. Eutrophication

• The excessive richness of nutrients (phosphorus, nitrates, and detergents) in a lake or other body of water that leads to acceleration in the growth of algae and the natural aging of the lake is known as eutrophication.

• Excess algal growth deoxygenates water leading to the death of aquatic life.
