The eutrophication of water body results in :
- (A)loss of Biodiversity✓ Correct
- (B)breakdown of organic matter
- (C)increase in biodiversity
- (D)decrease in BOD.
Answer: (A)
Solution
Eutrophication is the enrichment of water bodies with nutrients (especially nitrogen and phosphorus), leading to excessive growth of algae and aquatic plants.
The consequences of eutrophication include:
While breakdown of organic matter does occur during decomposition, the primary ecological consequence is the loss of biodiversity due to oxygen depletion and habitat degradation.
The answer is loss of Biodiversity.
The consequences of eutrophication include:
- Algal blooms that block sunlight
- Depletion of dissolved oxygen when algae die and decompose
- Death of aquatic organisms due to oxygen depletion
- Loss of biodiversity as sensitive species cannot survive
- Increase in BOD (Biological Oxygen Demand), not decrease
While breakdown of organic matter does occur during decomposition, the primary ecological consequence is the loss of biodiversity due to oxygen depletion and habitat degradation.
The answer is loss of Biodiversity.
