Answers
Explanation:
Various types of animals (herbivores, carnivores, omnivores) live in forests and contribute to food chain.
Interconnection of food chain will form food web. Following activities show how animals help forests 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 provides necessary minerals for plant growth.
Forest acts as a natural absorber of rainwater and allows it to seep because of roots of trees.
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.
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 necessary nutrient balance in the soil.
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.
Forests are excellent, perfect and natural recycling factories. All animals, whether herbivores or carnivores, depend ultimately on plants for their food.
Herbivores eat plants and their products. Carnivores eat herbivores.
Dead remains of animals and plants are decomposed by micro-organisms into humus.
Whatever is produced in the forest is ultimately utilized by different components of the forest.
There is a food chain in every ecosystem. Forests maintain a network of food chains called food web and hence nothing goes waste in a forest.
