With reference to Eurtorphication, sometimes seen in the news, consider the following statements:

1. It is characterized by excessive plant and algal growth due to overly enrichment of minerals and nutrients in the water body.

2. The overgrowth of algae may create a dead zone where no organisms can survive.

3. It is intensified due to huge quantities of organic load in the form of sewage.

Explanation:

Eutrophication, or hypertrophication is when a body of water becomes overly enriched with minerals and nutrients which induce excessive growth of plants and algae. This process may result in oxygen depletion of the water body. It also blocks light from reaching the water. This prevents the aquatic plants from photosynthesizing, a process which provides oxygen in the water to animals that need it, like fish and crabs.

The huge quantities of organic load in the form of sewage from nearby townships are regularly reaching the river system. This is contributing to the eutrophication resulting in the change of colour.
