Nature and man live in close co-existence. There are a number of factors that are interdependent and also sustain one another. All of these organisms have an extremely vital role to play and are important in their own respect. They maintain the numbers of other organisms in the food chain. thus in this cyclical existence, it is important to ensure that no one organism gets completely eliminated or it would result in huge disruption and chaos in the environment.
