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 ...

Dead organisms are broken down into smaller pieces by the process of decay. Organisms such as earthworms are involved in this process.

Complex organisms, thousands of times smaller than a grain of sand, can shape massive ecosystems and influence the fate of ...

an important fuel for other sediment-dwelling organisms such as methanogens (which include marine archaea) and heterotrophic bacteria. The products of these organisms feed back into the carbon cycle ...

A modeling study estimates that by drastically reducing fish biomass over the past century, industrial fishing may be affecting ocean chemistry, nutrient fluxes, and carbon cycling as much as climate ...

A study from the U.S. Geological Survey found the ecosystems on California's public lands are losing the carbon they've ...

Microbes in Peru’s peatlands regulate carbon cycle and influence climate Amazonian microbes could either mitigate or ...

Understanding how key players such as whales, plankton, seagrasses and other forms of sea life interact sheds light on Earth’s carbon cycle. Carbon, a chemical element, is found in all organic ...
