Question

Eutrophication is excess growth of

• A. Bryophytes
• B. Algae and aquatic plants
• C. Gymnosperms
• D. Pteridophytes

Answer 1

The correct option is B Algae and aquatic plants

Eutrophication is the phenomenon of nutrient enrichment of nitrogen and phosphorus in a water body that supports a dense growth of plants and animal life. Due to nutrient enrichment, excess growth of algae occurs which is called algal bloom. When these algae die, their organic matter gets decomposed and this results in the depletion of oxygen leading to death of aquatic animals. This process is called eutrophication.

So, the correct answer is 'Algae and aquatic plants'.
