Question

What is eutrophication? List its two harmful effects.

Answer 1

Eutrophication can have serious effects, like algal blooms that block light from getting into the water and harm the plants and animals that need it. If there's enough overgrowth of algae, it can prevent oxygen from getting into the water, making it hypoxic and creating a dead zone where no organisms can survive.

Answer 2

eutrophication is natural ageing of any water body eg.lake due to presence of excess nutrients..

it leads to extinction of aquatic organisms
