Excessive amount of nitrogen phosphorous in lakes is called as-

Correct option is B

The correct answer is (b) Eutrophic.
· Eutrophic refers to a water body, such as a lake or pond, that has an excessive amount of nutrients, particularly nitrogen and phosphorus.
· These nutrients promote the growth of algae and other plant life, leading to dense algal blooms, which deplete the oxygen levels in the water.
· This process, known as eutrophication, can result in the death of aquatic animals due to the lack of oxygen, and it significantly impacts the overall ecosystem of the lake or water body.
Additional Knowledge:
· Endotrophic: This term is not commonly used in the context of nutrient levels in lakes.
· Mesotrophic: Refers to lakes with an intermediate level of productivity, between oligotrophic (low nutrient) and eutrophic (high nutrient).
· Oligotrophic: Refers to water bodies that are nutrient-poor, generally deeper, and have low productivity, with clearer water and higher oxygen levels.
