The eutrophication of water body results in

Options

  1. AIncrease in biodiversity
  2. BLoss in biodiversity
  3. CBreak down of organic matter
  4. Ddecrease in BOD .

Correct answer

B. Loss in biodiversity

Step-by-step solution

The addition of phosphates in water enhances algae growth. Such profuse growth of algae, covers the water surface and reduces the oxygen concentration in water. This leads to anaerobic conditions, commonly with accumulation of abnoxious decay and animal death. Thus, bloom-infested water inhibits the growth of other living organisms in the water body. This process in which nutrient enriched water bodies support a dense plant population, which kills animal life by depriving it of oxygen and results in subsequent loss
