Biogeochemical Cycle
In ecology, a biogeochemical cycle is the alternative passage of a element or chemical compound of the organic state to the state Minéral within the Biosphère. The various cycles in interaction confer on the biosphere a capacity regulation, called Homéostasie. This one is at the base of the perenniality of the ecosystem S, thanks to the great stability which it ensures, all at least apart from the human interventions and exceptional phenomena geoclimatic.
Biogeochemical major cycle is connected to the Plate tectonics .
The most important cycles are:
- * the Cycle of the nitrogen
- * the Cycle of carbon
- * the Cycle of water
- * the Cycle of hydrogen
- * the Cycle of oxygen
- * the Cycle of phosphorus
- * the Cycle of sulfur
- * the Cycle of carbon
