(A) Photosynthesis in land plants fixes atmospheric CO2 (inorganic carbon) as organic carbon ... energy-rich food molecules and to produce oxygen.

However, photosynthesis doesn't just drive the carbon cycle — it also creates the oxygen necessary for respiring organisms. Interestingly, although green plants contribute much of the oxygen in ...

Carbon, which is found in the human body, takes an unusual journey after the demise of the the stars that create the element.

Complex organisms, thousands of times smaller than a grain of sand, can shape massive ecosystems and influence the fate of Earth's climate, according to a new study.

the process green plants use sunlight to absorb nutrients from carbon dioxide and water. This cycle therefore steadily speeds up oxygen production over the passage of Earth's history. The research ...

And like plants, they also release oxygen, contributing at least 50% ... forms of sea life interact sheds light on Earth’s carbon cycle. Carbon, a chemical element, is found in all organic ...

Scientists discovered microbes in Amazon peatlands that control carbon storage. If peatlands stay stable, they store carbon.

Cycling’s governing body has banned the repeated use of carbon monoxide rebreathing that some riders misuse to artificially increase their performances.

The IAEA Environment Laboratories apply nuclear and isotopic techniques to better understand the carbon cycle, to evaluate the ocean’s ... a region which is particularly sensitive to ocean warming, ...
