(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 ...

Billions of tonnes of carbon are constantly moving through the atmosphere, land and oceans. The ocean carbon cycle is a set of vital processes that helps regulate the Earth’s climate and support ...

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 ...

The emergence of life on our planet added a new layer to the carbon cycle. As plants grow, they take CO 2 out of the atmosphere, and when they die, it is released again. Animals that consume the ...

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 ...

If Earth's history were a calendar year, humans would not appear until the last few minutes before midnight on Dec. 31.

Diatoms are too small to see with the naked eye, yet they are one of the most productive algae species in the ocean and play an important role in the global carbon cycle. Using photosynthesis ...

Carbon dioxide is absorbed by producers to make carbohydrates in photosynthesis. Animals feed on plants, passing the carbon compounds along the food chain. Most carbon they consume is exhaled as ...
