Question
People say that nothing goes waste in a forest. Can you explain, how?
✓
Answer
Nothing goes waste in a forest because of the following reasons:
Dry leaves and remains of dead animals are converted to a dark coloured substance called humus and increase the fertility of soil. The importance of humus to the soil is that it provide nutrients for the growth of plants.
Dead animals become food for vultures, crows, jackals and insects.
Broken branches of trees are used as fuel by the people living in the vicinity.
