title: [Origin of biosphere].
abstract: Concepts of origin of life on the planet are briefly considered. The problem of origin of biosphere is discussed, with a suggestion that the origin of living organisms and biosphere are two aspects of the same process. There is put forward a hypothesis of embryosphere--the primary medium, in which preorganisms could appear. The ecosystemic approach to origin of life poses a question about sources of the matter and energy used by the primary life as well as about causes of the biochemical unity that exists in all Earth organisms.
