If a living system, or group of organisms, cannot adjust to an envirormental change, it will be out-competed by groups that can. The organism will have to find a new way to survive or it will die out, survival of the fittest.
The structures of living organisms is very complex and very different from one organism to another; species are classified to group similar kind of living organisms through knowing about their metabolic and catabolic activitiesThis makes it less complex to study the developmenthistory and science of evaluation of living organisms on earth.

Cyanobacteria is the most ancient group of organisms on this earth.
viruses and pirons -- it should be noted that these 'organisms' are in the grey area between living and non-living things.
