Answer:- (i) Biodiversity is immensely rich in wildlife and cultivated species, diverse in form and function, but closely integrated in a system through multiple networks of interdependencies.

It is important for human lives because the human beings, along with the biodiversity, form a complete web of ecological system in which we are only a part and are very much dependent on this system for our own existence.

industrial effluents, chemicals, wastes, etc. are also responsible for the depletion of flora and fauna.
