All plants, animals and human beings depend on their surroundings.
For plants, animals and human beings to survive, they must interact with the environment, which comprises living organisms and non-living components. Plant and animal kingdom together make the biosphere or the living world. All plants, animals and human beings depend on their immediate surroundings. Often they are also interdependent. ‘This relation between the living organisms, as well as the relation between the organisms and their surroundings form an ecosystem’. In every ecosystem, there is a perfect balance in transferring energy and matter among the different components. This is known as Ecological Balance.
