The next levels of life organization can be called the ecological levels. There are population, species, consortium, ecocycle, biogeocoenose (ecosystem), and biosphere levels. Historically, biosphere (protobiosphere) was the oldest form of ecological macrosystems; it was a direct extension of the geological cycle. Probably, from the very beginning, biosphere consisted of separate cycles (proto-biogoenoses). As a result of corpusclezation, small pieces of living matter took shape of cells, which developed to populations of living organisms.
