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 ...

Using this knowledge, the scientists built a unique sophisticated computer model to more accurately chart key changes ... nutrients from carbon dioxide and water. This cycle therefore steadily ...
