This process, called photosynthesis, is essential to the global carbon cycle and organisms that conduct photosynthesis represent the lowest level in most food chains (Figure 1). Most living things ...

(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 ...

The stunning estimate offers hope that natural ecosystems in pan-tropical forests could help humans control global warming.

Similarly, we might think of plants using carbon dioxide and sunlight for photosynthesis and producing oxygen and glucose. How can we determine whether carbon dioxide is actually being used or ...

An experiment in the Daintree rainforest found the rate of photosynthesis in leaves warmed by 4°C dropped by an average of 35 ...

Phytoplankton have been essential Earth life for over 35 billion years. Through photosynthesis, they consume carbon dioxide ...

The IAEA Environment Laboratories apply nuclear and isotopic techniques to better understand the carbon cycle, to evaluate the ocean’s capacity to store carbon ... take up CO 2 in the surface ocean ...

Photosynthesis can occur in surface plants ... seagrasses and other forms of sea life interact sheds light on Earth’s carbon cycle. Carbon, a chemical element, is found in all organic matter ...
