Question

Phosphate containing fertilisers cause water pollution. Addition of such compounds in water bodies causes __________.

Answer 1

Fertilizers contain phosphates as additives. 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 obnoxious decay and animal death. Thus, bloom-infested water inhibits the growth of other living organisms in the water body.

Hence, from the above analysis it is concluded that options (A) and (B) are correct.
