Excessive amount of nitrogen and phosphorous in lakes is called as -

The correct answer is Eutrophic.

In News

• Excessive amounts of nitrogen and phosphorus in lakes can lead to eutrophication, causing harmful algal blooms and oxygen depletion.

Key Points

• Eutrophic lakes are rich in nutrients, particularly nitrogen and phosphorus.
• These nutrient-rich conditions lead to an abundance of plant life, especially algae.
• Eutrophication can result in oxygen depletion in the water, harming aquatic life.
• Eutrophic lakes are often a result of human activities such as agriculture and wastewater discharge.

Additional Information

• Endotrophic
  • Not a standard term in limnology (study of inland waters).
• Mesotrophic
  • Refers to lakes with an intermediate level of productivity.
  • These lakes have moderate levels of nutrients and biological activity.
• Oligotrophic
  • Refers to lakes with low nutrient levels and low productivity.
  • These lakes are often deep with clear water and support less plant life.
