Question Question 4
What is meant by eutrophication? How does it affect aquatic life?
Eutrophication refers to excessive growth of algae and aquatic plants in water bodies. It occurs due to introduction of nutrients and chemicals through discharge of domestic sewage, industrial effluents and fertilizers from agricultural field. It causes depletion of oxygen and reduction of light and heat in the water bodies which results in death of aquatic animals and rotting of plants.
