Question

Which one of the following is NOT an indicator of the degradation of a water body?
a) Increased transparency
b) Decreased species diversity
c) Increased sedimentation
d) Decreased oxygen concentration​

Answer 1

GREEN INVADERS

• Option (a) Increased transparency is correct.
• Answer: Increased transparency is NOT an indicator of the degradation of a water body.

• Supportive sentences: The environmentalists say that invasive species like water hyacinth have clogged this water body. Also, the discharge of sewage into the lake has resulted in the growth of unwanted plants. This is blocking the air-water interface, thereby reducing the dissolved oxygen in the water and killing a lot of fish. The water bodies clogged by the invasive species also become a breeding ground for mosquitoes.

Answer 2

Increased Transparency is not an indicator of the degradation of a water body.

Explanation: Answer A

• Among all the following options, only answer a) that is, Increased Transparency is not a direct sign of indication for degradation.
• Decreased species diversity means that the animals in the water body has perished due the poor quality of the degraded water body.
• Increased Sedimentation also shows that the water body has been sullied by sediments and debris which makes the water unsuitable for use.
• Decreased oxygen in water also indicates degradation of water as more oxygen means that the water is purer and cleaner and more appropriate for water- species.
