Forests are the essential life on earth. All plants and animals continue to live in forest life. Forest plays an important role in the ecological balance, environmental balance etc. Each and every living being in the forest is interconnected so that carbon dioxide and oxygen cycle will be balanced and when anyone among them is out of balance it results in the entire organisms to be weakened. When animals and plants die, the various microorganisms present in the soil helps to convert the dead and decayed matter into humus and thus the fertility of soil can be increased which boosts up the plant growth. All food chains and food webs need the variety of plants and animals.
