Definition of Eutrophication

Eutrophication is the excessive growth of plants as well as algae in the water bodies. This happens when the limiting growth factors that are required for the process of photosynthesis are available in an excessive amount. The growth factors include sunlight, fertilizers, and carbon dioxide. It occurs naturally in the lakes as they become quite old and when they are filled with sediments of nutrients. Yet, excessive and increased human activities have accelerated the rate of eutrophication.


The fisheries, sources of potable water, and recreational water bodies are getting damaged and degraded by this. The algal blooms deteriorate the quality of water and the penetration of light is also decreased due to which the survival of organisms present in water bodies is compromised.
