However the amount of carbon in a specific reservoir can change over time as carbon moves from one reservoir to another.
The schematic shows the major reservoirs of carbon in gigatons of carbon gtc 1 gtc 1 pgc. Group of answer choices. The biggest changes in the land carbon cycle are likely to come because of climate change. The carbon cycle is the cycle by which carbon moves through our earth s various systems.
Plants take up co 2 from the atmosphere and convert it to carbon in plant tissue and oxygen. It continuously reuses and recycles carbon in the ecosystem. Plants also respire to generate energy for life. Petagram of carbon and the major fluxes in gtc yr.
Both factors have led to some additional plant growth. Since the industrial revolution approximately 150 years ago human activities such as the burning of fossil fuels and deforestation have begun to have an effect on the carbon cycle and the rise of carbon dioxide in the atmosphere. Because earth is a closed system the amount of carbon on the planet never changes. He was seeking to understand the causes of ice ages.

D the global carbon cycle is the only. The carbon cycle involves the movement of carbon between the atmosphere biosphere oceans and geosphere. C carbon can be recycled only a olimited number of times. C more atmospheric carbon dioxide means that there is less carbon available for the growth of terrestrial plants.
Why are changes in the global carbon cycle important. Change and the global carbon cycle the global carbon cycle is driven by geologic processes and by photosynthesis and the respiration of plants and animals figure 2 24. For example some carbon in the atmosphere might be captured by plants to make food during photosynthesis. What motivated arrhenius to calculate how changes in carbon dioxide might affect the climate.
Using only pencil and paper calculations arrhenius concluded that a doubling of the carbon dioxide concentration would raise global temperatures by about. It causes climate change and increase in the global temerature. Carbon dioxide increases temperatures extending the growing season and increasing humidity. A schematic from the ipcc ar4 report is shown here.

B carbon is the chief source of food and burning it reduces available food for primary consumers. Why are changes in the global carbon cycle important. A atmospheric carbon means that there are less fossil fuels available.
