Autotrophs participate in the carbon cycle by fixing carbon ... pathway is the Calvin–Bassham–Benson cycle, which is present in plants, algae, cyanobacteria and proteobacteria.

Scientists have analyzed whether planting turf and clover beneath solar panels can increase soil organic carbon, after measuring the results from a commercial plant in Japan. They tested more than 20 ...

Rapid climate shifts are causing unexpected biodiversity changes across Arctic tundra, reshaping fragile ecosystems ...

Frequent heat and drought events in southwestern Europe are reducing ecosystems' capacity to absorb CO₂, according to a ...

The amount of carbon found in living plants and animals is comparatively ... due to the unknown consequences on global nutrient cycles and marine ecosystems (Cullen & Boyd 2008).

Plants, key players in climate regulation, could see their role disrupted by global warming. A study reveals that rising ...

The IAEA Environment Laboratories apply nuclear and isotopic techniques to better understand the carbon cycle, to evaluate the ocean’s capacity to store carbon ... phytoplankton (microscopic marine ...

To test the influence of shrubs on the carbon cycle, the team created two plots in Alaska that excluded animals. The first, near Nome, had greater plant cover than the second site near Toolik Lake.

The emergence of life on our planet added a new layer to the carbon cycle. As plants grow, they take CO 2 out of the atmosphere, and when they die, it is released again. Animals that consume the ...

Ocean ecosystems play a critical role in carbon storage and oxygen generation. Some of these ecosystems are under threat; others remain unexplored. Understanding how key players such as whales ...

Animals feed on plants, passing the carbon compounds along the food chain. Most carbon they consume is exhaled as carbon dioxide during respiration. The animals and plants eventually die.
