Forests play an important role in maintaining the balance between oxygen and carbon dioxide in the atmosphere. Forest works like a self-sustaining system. Whatever is produced in the forest is utilized by different components of the forest. Animals during respiration take in oxygen and release carbon dioxide. Plants take in carbon dioxide and release oxygen through the process of photosynthesis. Even the waste is converted into beneficial substances in a forest. Due to this, there is no waste in a forest.
The micro-organisms which convert the dead plants and animals to humus are known as decomposers. Examples: Fungi and Bacteria. Decomposers recycle and convert the dead matter into humus which mixes with forest soil and provide necessary nutrients to plants. Thus decomposers help in maintaining the nRead more

Forest acts as a natural absorber of rainwater and allows it to seep. When rainwater falls on leaves of trees and plants, it does not fall directly on the ground. It drips slowly on the forest ground (does not stagnate) and hence prevent floods. https://www.tiwariacademy.com/ncert-solutions/class-7/Read more

Various types of animals (herbivores, carnivores, omnivores) live in forests and contribute to food chain. Following activities show how animals help forest grow and regenerate. • Animals help in dispersal of seeds from one part of the forest to other part. • Animal’s excreta and their dead bodies wRead more
Various types of animals (herbivores, carnivores, omnivores) live in forests and contribute to food chain. Following activities show how animals help forest grow and regenerate.
• Animals help in dispersal of seeds from one part of the forest to other part.
• Animal’s excreta and their dead bodies when decomposed into soil act as manure for the plants.
• Microorganisms convert dead plants and leaves into humus which is rich in nutrients. Humus in soil provide necessary minerals for plant growth.
