Prove that a species is discrete.

A biological species is the smallest indivisible structural unit of living things. Any species consists of populations. This is a collection of organisms of the same species that live on the same territory. Populations may differ from each other. Differences in populations arise due to different habitat conditions. So biotic and abiotic factors affect the external and internal structure of individuals in the population. That is why the biological species has the properties of discreteness. The discreteness of the species also denotes the fragmentation of the species.
