Autotrophs participate in the carbon cycle by fixing carbon dioxide to produce the biomass that all other organisms use for life. Four autotrophic carbon-fixation pathways were already known and ...

(A) Photosynthesis in land plants fixes atmospheric CO2 (inorganic carbon) as organic carbon, which is either stored as plant biomass or in soil, or is decomposed back to CO2 through plant and ...

The principles of chemical oceanography provide insight into the processes regulating the marine carbon cycle. The text offers a background in chemical oceanography and a description of how chemical ...

The atmosphere is only one part of Earth's larger carbon cycle. The cycle also involves the ocean, plants, animals, rocks and decaying organisms. While the ocean absorbs vast amounts of carbon ...

as part of what is called ‘the global carbon cycle.’ A change in any of these fluxes could have wide-ranging impacts on ecosystems and our climate. The IAEA Environment Laboratories apply nuclear and ...
