(i) Populations of organisms live in well defined place called niches in the ecosystem and divide using their ability to reproduce.
(ii) Reproduction involves DNA copying which is the source of information for making proteins thereby controlling body design.
(iii) These body designs allow the organism to use a particular niche for the stability of the population of a species.
(iv) (Minor) variations may also lead to the stability of the species.
