Question

what do you mean by ph scale how animals and plants protect themselves from their enemies through chemical warfare​

Answer 1

The pH scale ranges from 0 (most acidic) to 14 (most basic), with the value of 7 representing neutral solutions. Most animal species cannot survive if the water is too acidic (generally below 5.0), or too basic (above 9.0). Optimal pH for many species is between 7.0 and 9.0.

In response to being eaten, plants release chemicals which warn nearby members of the same species that herbivores are about. These plants are able to activate defence genes, reducing their vulnerability. The wounding hormone, called jasmonic acid, is used to co-ordinate a chemical response.
