    Carbon (C) atom is unthinkable without the life. Living things are the main carbon source of carbon dioxide (CO2) creates. Nature of carbon dioxide, through photosynthesis, land and sea birds, marine animals for the formation of the shell, the bottom of the death and the collapse of marine animals, sea and lakes are consumed Upon storage in carbonate rocks. Of carbon dioxide consumed again return to nature, living things breaths, organic substances burn, rot, coal, hydrocarbon fuels such as wood, carbon formations produced by the use of artificial fertilizers, as a result of human activities and where the atmosphere is due to the carbon dioxide. Natural mechanisms of carbon dioxide consumed in a variety of mechanisms to return to nature again, "" carbon cycle "is called".
    The sole source of carbon used by plants through photosynthesis are synthesized compound (CO2) is. 30-40 years, but the phenomenon of photosynthesis is very complex and is known. (Melvin Calvin, Nobel Prize 1961) in 1 mol glucose into CO2 6Mol up to 100 digits in the net reaction occurs through the conversion is as follows: 6 CO2 +6 H2O ------- C6H12O6 +6 O2
    Net reaction is quite endotermiktir.Gerekli sağlanır.Hayvanlar plant consume energy from sunlight, carbon atoms in the carbon part geçer.Bir animals, through animal respiration, in the form of CO2 into the air and the plants died geçer.Hayvanlar kısımCO2 also still a part of the atmosphere of the decaying organic geçer.Karbonun substances kept in the coal, oil, natural gas in the form of fossil fuels over the oceans dönüşür.CO2 does enter the cycle of CO2 through photosynthesis in the plant plankton and other organisms convert organic compounds, plankton, a large part of yerler.Karbonun, carbonate rocks (mainly CaCO3) in the form of storage yumuşalçaların eskidenizlerdeki edilmiştir.Bu rocks formed from the shells.
    New research shows that, humid places and rivers in the Rainforest of South America, until the carbon dioxide absorbed back into the atmosphere each year is dry regions. Results of a carbon balance of all the Amazons, and other tropical forests as a whole. Carbon dioxide is an important greenhouse gas. This is also the researchers, industrial activity will help them find the effect of global warming and deforestation.
    Jeffrey Richey of the University of Washington in Seattle, "We have identified another source of carbon dioxide, this will create an imbalance in the system a little bit more," he says. Richey and his colleagues, which is half the size of Europe (1.8 million square kilometers) of Amazon on the moist areas of carbon dioxide, water örneklediler. Some swampy areas, carbon dioxide bubbles can occur if you go out, swamps and rivers of gas produced by bacteria in decaying wood and degraded areas, they add.
    Richey and colleagues, at different times of the year, the Amazon River and bataklarındaki propagation, satellite-based technique haritalandırdı. By combining these measurements of the levels of carbon dioxide in water, moist areas, calculated how much carbon dioxide is set free.
    <England at Edinburgh University researcher Yadvnder Malhi carbon cycle, "we hope the water is a larger source of carbon dioxide," he said, and so far overlooked the role of the water, he said.
    Geologist, Eric Woods, a researcher at Hole'de Sundquiste, this study is that Amazon's true that while a carbon balance, so that it is difficult to calculate a broad range of input-output, he says. But the global measurements, shows that the balance of carbon sources for tropical forests.
    Global climate changes, scientists working to identify and prevent them, how much carbon dioxide soğrulup been released into the tropical forests, requires no definitive findings.
    Richey and colleagues measured by, the destruction of tropical forest regions, 166 billion tons of carbon dioxide into the atmosphere each year in the form of carbon added. To find 5 billion tons of industrial emissions. And humid regions of the Amazon Nehirleri'nde consists of 500 million tons of carbon. The discovery of new sources of carbon have shown that the contribution of forests in climate regulation more vital than had been supposed.
    According Sundquiste, people can easily change the role of interventions in the water as a source of carbon. These methods can easily be affected by the destruction of the forest. Forest destruction of the soil increases erezyonunu. Erosion of organic substances, can flow from rivers and marshes, and their carbon output may increase more. Or you can keep the organic materials in sediments and therefore prevent rotting.
