Question

Explain the process of eutrophication of a water source.

Accepted Answer

The loss of dissolved oxygen due to the excessive enrichment of nutrients in water bodies is called eutrophication. The excessive growth of algae and plankton in a water body are indicators of this process. This can cause problems along the food chain and affect any animal that feeds on them. The process of eutrophication of a water source can be explained as follows-

The nutrients and fertilisers reach the water bodies due to surface run-off water.

The excess amount of nitrogen and phosphorus promotes the excessive growth of algae and phytoplankton on the water surface.

This causes the lack of availability of sunlight, oxygen, and other nutrients and resources to the aquatic plants and animals that live deep in the water bodies.

Therefore, the life of aquatic organisms is affected and the population of aquatic organisms decreases.
