The process of 'eutrophication' is due to
Options
- Aincrease in concentration of radioactive substances in water
- Bthe reduction in concentration of the dissolved oxygen in water due to phosphate pollution in water
- Cincrease in concentration of fluoride ion in water
- Dincrease in concentration of insecticide in water
Correct answer
B. the reduction in concentration of the dissolved oxygen in water due to phosphate pollution in water
