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 ...

(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 ...

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 ...

Diffusion happens naturally and so does not require energy. Substances like oxygen, carbon dioxide and glucose move in and out of cells by diffusion. If I spray a little perfume over here, ...

The study highlights the urgent need to safeguard global tropical wetlands from human impact. Complex organisms, thousands of ...

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 ...

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 ...
