Rivers, lakes and wetlands are important factors for climate change, which should have a place in conceptual models of the global carbon cycle. A broader concept of a 'boundless carbon cycle ...

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 ...

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 ...

Animals feed on plants, passing the carbon compounds along the food chain. Most carbon they consume is exhaled as carbon dioxide during respiration. The animals and plants eventually die.

A research team has made significant discoveries regarding the complex reaction mechanisms of carbon dioxide (CO2) in supercritical water. These findings are crucial for understanding the molecular ...
