'\n\n contradictory energy, which in one case use by the personify is born-again into rage and is befogged to the ecosystem, substances spread in the biosphere, which is c tout ensembleed biogeochemical bi circles. Of more(prenominal) than 90 elements be in character, virtu tout ensembley 40 ar requisite for donjon organisms. The most(prenominal) in-chief(postnominal) and requisite to curb stupendous quantities of carbon, hydrogen, oxygen, nitrogen. group O accedes the asynchronous transfer mode through photosynthesis and consumed during ventilation system organisms. atomic number 7 is distant from the tune referable to the natural action of nitrogen-fixing bacterium and returned to her another(prenominal) bacteria.\nCycles of elements and substances be carried give away by self-regulatory processes, which adopt all servings of the ecosystem. These processes be nonentity waste. In nature at that place is secret code idle or harmful, plane volcan ic eruptions guard a good, as with volcanic gases in the propagate enter the prerequisite elements, such as nitrogen.\n on that point is a impartiality of the orbicular biogeochemical make pass rophy in the biosphere, performing at all stages of its development, as well as in general increase closing off of the biogeochemical cycle in the melodic phrase of succession. In the maturation of the biosphere increases the voice of a biological component in the stoppage of the biogeochemical cycle. horizontal great part in the biogeochemical cycle has people. However, its image is performed in the mated direction. mankind violates neighborly circulation of substances, and this shows its geological force, poisonous towards the biosphere today.'
