Biosphere carbon
WebA positive value indicates that a sphere (e.g., atmosphere, hydrosphere, and biosphere) has gained carbon (i.e. that sphere is acting as a carbon sink). The atmospheric, ocean, and terrestrial biosphere can have positive or negative values since they can act as sources or sinks. You might be wondering why we are not working with data more ... WebCarbon is cycled through the terrestrial biosphere with varying speeds, depending on what form it is stored in and under which circumstances. [3] It is exchanged most quickly with the atmosphere, although small amounts of carbon leave the terrestrial biosphere and enter the oceans as dissolved organic carbon (DOC).

WebThe movement of nutrients through the biosphere is different from the transfer of energy because, whereas energy flows through the biosphere and cannot be reused, elements are recycled. The same atoms of carbon or nitrogen may, over the course of eons, move repeatedly between organisms, the atmosphere, the soil, and the oceans. WebIn other words, fossil fuel use increases the total amount of carbon in the biosphere-atmosphere system while bioenergy systems operates within this system; biomass combustion simply returns to the atmosphere the carbon that was absorbed as the plants grew.*. The net greenhouse gas (GHG) outcome of using biomass for energy cannot be …
