From the point of view of ''Evidence-Based Science'', there is only life on our planet. The ecosystem, in my concept, is the basic unit of life, which occupies a place on our planet (biotope) with physical and chemical conditions (habitat) and the living beings in it (biocenosis in Russian, biodiversity in American and biological diversity in Venezuelan).

That is, there are only ecosystems on Mother Earth (official UN name). Life and ecosystems emerged millions of years ago in the primordial sea and when the ozone layer gained our atmosphere, they made the great leap to the emerged territory, establishing such an extensive variety in space and time.

Living beings are established on the basis of a relationship with the habitat and biological diversity, evolving with their new situations. This is how in several epochs it replaces the integrating species, essentially establishing the substitution over time, some species for others, until reaching the maximum capable equilibrium, the Climax Ecosystem.

When colonizing some form of life, the ecosystem is established, it begins to relate to the habitat and to other colonizing species, thus forming an initial vulnerable ecosystem, perhaps with little adaptation.

This ecosystem evolves, the more it adapts to the system and the surrounding spatially or functionally related, evolving towards stability or the formation of a new type of members and functions until '''maturity'''.

Experts attribute this balance to a greater coupling and use of energetic, material and biological factors, which upon reaching the Climax Ecosystem acquires the trophism as a whole, a highly complex process, with high levels of resilience if it establishes a biome or bioregion with other Climax Ecosystems.

This ecosystem that reaches the peak of its equilibrium and achieves its maximum complex of interdependence and trophism, is in many cases, difficult to restore and its disappearance may be forever because the community (set of species living together in an ecological unit) that lives in it, is a Climax Community coming from the process of origin of species, natural selection and evolution under circumstances that will never happen again.
