There are millions of living organisms on planet earth. All these living organisms, including man, are interdependent on each other. All living organisms and the natural resources make a complex web of ecosystem.
Plants, animals and micro-organisms purify the air we breathe, the water we drink and the soil that helps us grow food. Plant life is called the primary producer in the ecosystem as all living things depend on them in one way or the other. The forest where plant life is in abundance is very important for the existence of man.
