(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 ...

Nearly all elements except hydrogen and helium—including carbon, oxygen and iron—only exist ... get pulled back in and continue the cycle of star and planet formation." Garza is lead author ...

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 ...

A research team has shown that methanogens, micro-organisms ubiquitous in low-oxygen environments like aquifers, soil and even permafrost, can propel their growth by dissolving calcium carbonate, one ...

low-oxygen conditions of tropical peatlands in Peru's northwestern Amazonian rainforest. The new research shows these microbes have a dual role in the carbon cycle and the potential to either ...

Carbon dioxide is made up of one carbon atom covalently bonded to two oxygen atoms. Although electrons are shared, they are not shared equally between the carbon and the oxygen atoms. The oxygen atom ...
