उत्तर
If the living components of the environment do not exist, then the food chain and food web will not function. Some species will go extinct. Living things were produced on earth many million years ago. It is not possible to get them back by man-made processes. If the balance in nature is disturbed, it will affect human beings too. Therefore, it is important to conserve the living components of the environment.
