Science Chapter 12: Forests: Our Lifeline

We get various products from the forests surrounding us. Forest is a system comprising various plants, animals and micro-organisms.

In a forest, trees form the uppermost layer, followed by shrubs. The herbs form the lowest layer of vegetation. Different layers of vegetation provide food and shelter for animals, birds and insects.

The various components of the forest are interdependent on one another. The forest keeps on growing and changing, and can regenerate. In the forest, there is interaction between soil, water, air and living organisms.

Forests protect the soil from erosion. Soil helps forests to grow and regenerate. Forests are the lifeline for the forest-dwelling communities. Forests influence climate, water cycle and air quality.
