There is a kind of integrated system which is network of interdependencies between the flora and fauna so, let՚s say there are N number of trees in the region and half of them are cut then, due to this deforestation the fauna would be affected and there would be decrease in the wild life that is present in that region that means all the systems of a biodiversity are closely interrelated and there is a kind of multiple network of interdependencies that exist between the various flora and fauna.

India is among the world՚s richest bio diverse nations with nearly 8 % of the world species that are present in India.
