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

According to the calculations run by Ozaki and Reinhard, the oxygen-rich habitable history of Earth could end up lasting for ...

Rising temperatures make plants lose more water, weakening their ability to absorb carbon dioxide and survive heat stress.

During the process of photosynthesis, cells use carbon dioxide and energy from ... photosynthesis doesn't just drive the carbon cycle — it also creates the oxygen necessary for respiring organisms.

Both need water and air. We often think of animals using oxygen and glucose for cellular respiration and producing carbon dioxide. Similarly, we might think of plants using carbon dioxide and sunlight ...

Ocean ecosystems play a critical role in carbon storage and oxygen generation ... and in Earth’s most abundant greenhouse gases — carbon dioxide (CO2) and methane (CH4).

This meant that the “geological carbon cycle” would be a ... organic carbon in the rocks to oxygen in the air and water, which would react and release CO2. Knewz.com noted that measuring ...

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 new research shows these microbes have a dual role in the carbon cycle and ... hydrogen and CO2 that other microbes use to generate methane. Their ability to survive both oxygen-rich and ...
