Explain the term eutrophication with suitable example

टीपा लिहा

उत्तर

Eutrophication refers to alteration in the life of aquatic ecosystem due to increase in the concentration of certain organic compounds such as nitrates and phosphates. This generally occurs when fertilisers from a field are washed off by rainwater or irrigation to nearby ponds or rivers.
Example: Sudden increase in the population of algae or phytoplanktons in water body due to increase in the level of nutrients in water.
