Justify the statement ‘plants and animals are pH sensitive’ by giving two examples.

Answer :

Plants grown in soil depend a lot on the nature of the soil. Plants cannot grow in the soil which is more alkaline and having a pH greater than 7.

On the other hand, animals require to maintain the pH level in their stomach for the digestion process to get completed smoothly as digestion occurs at a particular pH only. If the level is disturbed then problems like acidity etc can be faced.


Hence even a small change in the pH level can affect the metabolic functioning of the animals as well as plants. In the following figure, it is visible how the pH affects the growth of the plant in soil.
