The meaning of CARBON CYCLE is the cycle of carbon in the earth's ecosystems in which carbon dioxide is fixed by photosynthetic organisms to form organic nutrients and is ultimately restored to the inorganic state (as by respiration, protoplasmic decay,
The meaning of CARBON is a nonmetallic chemical element with atomic number 6 that readily forms compounds with many other elements and is a constituent of organic compounds in all known living tissues —often used before another noun. How to use carbon i
The nuclides carbon-12 and carbon-13 are of importance in theCNO cycleof energy creation in certainstars. The cycle can be summarized in terms of nuclear equations, the separate steps being: Summation of the equations allows thefusionprocess to be written as a reaction among four atoms of hyd...
Respiration is the next step in the cycle, and unlike photosynthesis, it occurs in plants, animals, and even decomposers. Although we usually think only of breathing oxygen when we hear the word "respiration," it has a broader meaning that involves oxygen. To a biologist, respiration is the...
Two factors explain this development: First, the reduced utilization and/or a gradual replacement of oil-fired power plants, and second, a shift to the less carbon-intensive natural gas combined cycle power plants, which are today very popular in North Africa. The average specific CO2 emissions...
but perturbations to the long-termcarbon cycle, including major outgassing and weathering episodes, are an integral part of the overall picture and may be, in some instances, a prime cause. That we are causing one such major perturbation right now is an indication of the footprint we ourselves...
S7), meaning microbial growth, efficiency, and turnover tended to be greater in soils with more carbon per unit nitrogen. This indicates that our plots, as well as the soil used in our experiment (C:N = 12.0), fell below the stoichiometric boundary (i.e., threshold element ratio) ...
There has been research that linked the urban metabolic framework to footprint analysis by combing MFA with life-cycle approaches (such as LCA and IOA) and evaluated the environmental impacts of cities, for example, the works of Hillman and Ramaswami21, Goldstein et al.52, as well as other...

The meaning of CARBON-NEUTRAL is having or resulting in no net addition of carbon dioxide to the atmosphere : counterbalancing the emission of carbon dioxide with carbon offsets. How to use carbon-neutral in a sentence.
