carbon cycle

n.
2. Ecology The combined processes, including photosynthesis, decomposition, and respiration, by which carbon as a component of various compounds cycles between its major reservoirs—the atmosphere, oceans, soil, rocks, and living organisms.

carbon cycle

n
1. (Biology) the circulation of carbon between living organisms and their surroundings. Carbon dioxide from the atmosphere is synthesized by plants into plant tissue, which is ingested and metabolized by animals and converted to carbon dioxide again during respiration and decay
2. (General Physics) four thermonuclear reactions believed to be the source of energy in many stars. Carbon nuclei function as catalysts in the fusion of protons to form helium nuclei

car′bon cy`cle


n.
1. the biological cycle by which atmospheric carbon dioxide is converted to carbohydrates by plants and other photosynthesizers, consumed and metabolized by organisms, and returned to the atmosphere through respiration, decomposition, and the combustion of fossil fuels.
2. a cycle of nuclear transformations in stellar interiors through which hydrogen is converted into helium.

carbon cycle

carbon cycle

The continuous process by which carbon is exchanged between organisms and the environment. Carbon dioxide is absorbed from the atmosphere by plants and algae and converted to carbohydrates by photosynthesis. Carbon is then passed into the food chain and returned to the atmosphere by the respiration and decay of animals, plants, and other organisms. The burning of fossil fuels also releases carbon dioxide into the atmosphere.

2.carbon cycle - a thermonuclear reaction in the interior of stars
thermonuclear reaction - a nuclear fusion reaction taking place at very high temperatures (as in the sun)

The third sector should be dedicated to the study of forest management through the creation of a world-class forest carbon research institution to push the frontiers of understanding of the workings of forest carbon cycles, including production of the highest quality (and highest value) carbon credits, building on Oregon's overwhelming leadership in forest carbon production.
The carbonate-silicate cycle the authors are referring to is the evolution of rock through processes like sedimentation and weathering, a substantial part of the way carbon cycles through the global ecosystem.
By studying the sources of organic carbon exported by rivers and the way they change with time, we can begin to understand how the biospheric and geologic carbon cycles are connected.
The tiny amount of soil moisture links the planet's overall environmental systems - its water, energy and carbon cycles - as well as determines whether particular regions are afflicted with drought or flooding.
Data from SMAP will be used to enhance understanding of processes that link the water, energy and carbon cycles, and to extend the capabilities of weather and climate prediction models including improved flood prediction and drought monitoring capabilities.
Carbon responses vary depending on harvesting intensity, surface disturbance, and soil type, but the new findings indicate that such analysis should include a consideration of forest carbon cycles, researchers say.
Natural biological carbon cycles, on the other hand, run at seasonal or annual time scales - we can see them happening in our daily lives: photosynthesis in green leaves, respiration, veldfires and combustion of wood, rotting plants, and so on.
