Q. 104.1( 7 Votes )
Why the flow of acid rainwater into a river make the survival of aquatic life in the river difficult?
Answer :
The aquatic life survives in an optimum pH value. It is difficult for the aquatic life to maintain their metabolism in a pH value greater or less than the optimum pH value. When acid rainwater flows into a river it makes the river water acidic and disturbs the pH from its optimum value due to which the survival of aquatic life in the river becomes difficult.
