In biology species can become isolated from other species through a number of processes. These isolation processes keep the two species from interbreeding and producing hybrid offspring. There are five separate isolation processes that prevent two species capable of producing offspring from being able to do so. Ecological Isolation Ecological‚ or habitat‚ isolation is when two species that could interbreed do not because the species live in different areas. For example‚ in the wild of India both
