Organisms that belong to the same species can breed with each other. When they have offspring, the offspring belong to the same species as their parents .

Organisms that belong to different species cannot usually breed with each other .

But very occasionally two organisms from different species do breed with each other . This might happen in a zoo , where two animals from different species are put into the same enclosure . Their offspring are hybrids of the two species.

For example , a male lion and a female tiger in a zoo will sometimes breed together , if they don 't have a member of their own species to breed with . The young animals that are produced are called ligers.

Ligers , like all hybrids between two different species, cannot have offspring. They are infertile.

Replying to

As the earth system changes over time, individual species respond to these changes. In some cases, species disperse to new locations that match their preferred habitats.
Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species.
Furthermore, many hybrid organisms are sterile, meaning they cannot produce offspring.
Taxonomists identify, describe, and classify species using morphological, behavioral, genetic, and biochemical observations.
A species consists of a population (or populations) that cannot interbreed successfully with another species.
