Given below are two statements:Statement I: The nutrient deficient water bodies lead to eutrophication.Statement II: Eutrophication leads to decrease in the level of oxygen in the water bodies.In the light of the above statements, choose the correct answer:
- ABoth Statement I and Statement II are true
- BBoth Statement I and Statement II are false
- CStatement I is correct but Statement II is false
- DStatement I is incorrect but Statement II is true
Solution & Step-by-step Explanation
[Image showing the stages of eutrophication in a lake]Statement I is false: Eutrophication is the natural aging of a lake by biological enrichment of its water. It is caused by nutrient enrichment (especially Nitrogen and Phosphorus), not nutrient deficiency.Statement II is true: The excess nutrients cause algal blooms. When these plants die, their decomposition by bacteria consumes vast amounts of dissolved oxygen, leading to the death of fish and other aquatic life.
