Explanation:

Biodiversity can be defined as the variety or variability of species of flora and fauna in an ecosystem. A larger number of plant species or flora contributes to the greater variety of crops also some of the animal or faunal species are source of food for human beings.

The biodiversity involves the distribution of energy in the form of food in an ecosystem. This circulation is facilitated by the food chain when one organism is consumed by the other. Thus the direct ecosystem service of biodiversity is the distribution of energy among the organisms.

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.
