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.

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.

biology is the study of life. it is the study of living organism.
