Answer 2

Hello!

$\boxed{\sf Plants\:and\:Animals\:are\:pH\:Sensitive}$

Living organisms can survive only in a narrow range of pH change, our body works normally within a pH range of $\textbf{7.0}$ to $\textbf{7.8}$

When pH of rain water goes below $\textbf{5.6}$
It is called an Acid rain. When acid rain flows into the rivers, it lowers the pH of te river water and makes survival of aquatic life difficult.
