Cycle, biochemical biogeochemical

The evolution of life on Earfh has depended on a sustained supply of nutrients provided by the physical environment. Life, in turn, has profoundly influenced the availability and cycling of these nutrients hence the inclusion of bio in biogeochemical cycles. The involvement of the biosphere with biogeochemical cycles has been determined by the evolution of life s biochemical properties in the context of the physical and chemical properties of planet Earth. 

System 13. soil-plant cycle soil-forming geological rocks (I) soil (IV) soil living matter (community of soil organisms) (V, VI, VII) aerosols, atmosphere air (12a, III) plants (VIII) their biological reactions, endemic diseases (VIII). In the complex system 13, the inner relationships and biochemical and biogeochemical mechanisms are shown for natural and agroecosystems. The system 11 and link IX show the ways for interrelation of system 13 with terrestrial animals.

Biogeochemical cycles interact with each other extensively in space and time. This is true not only for C, H, and O, which are cycled by the same two processes of photosynthesis and respiration, but also for cycles that are driven by different biochemical processes and performed by distinct microorganisms. 

By focusing on a molecular elucidation of key biochemical processes in the marine biogeochemical cycles of elements, marine bioinorganic chemistry should help us understand the subtle and complex interdependence of marine life and ocean geochemistry, and how they have evolved together over the history of the Earth.
