Life appeared in the aquatic environment, but not before being prepared for the emergence of the first living beings. Since the emergence of life the whole Planet Terra has been modified in the relationship between biotic and abiotic.Biosphere represents life as a planetary phenomenon, and the life has as environment the Ecosphere . Both the vital phenomenon and Ecosphere had a coevolution during the geological time. Biocoenosis together with its biotope form an ecosystem. Ecosystem is the most beautiful and compelling example of what it means the unity of life and its environment, whether we think of bioskene, biochorion or biome.The species occupies a certain area, which represents its life environment (the entire complex of abiotic factors). Also , the individual has its life environment. We should call it habitat, but this term is often used differently in different comprising spheres.However, every living being, every individual, regardless of what species, Phylum or Kingdom is part of has its life environment, a proper environment,achieved by selection in a much more comprehensive environment.This environment has two parts harmoniously combined, forming a unitary whole: the Umwelt and the Innenwelt . So in one and the same environment ( broad ) each species realizes its own living environment as each individual realizes its life environment in a broader environment in which it lives..
