Are plants and animals pH sensitive?

-Our body works within the pH range of 7.0 to 7.8. 

-Living organisms can survive only in a narrow range of pH change.

 -When pH of rain water is less than 5.6, it is called acid rain. 

-When acid rain flows into the rivers, it lowers the pH of the river water.

-The survival of aquatic life in such rivers becomes difficult
