The atmospheric carbon cycle accounts for the exchange of gaseous carbon compounds, primarily carbon dioxide (CO 2), between Earth's atmosphere, the oceans, and the terrestrial biosphere.It is one of the faster components of the planet's overall carbon cycle, supporting the exchange of more than 200 billion tons of carbon (i.e. A large tree will absorb much more carbon than 48 pounds per year. Any green living plant absorbs carbon dioxide, extracts the carbon and releases the oxygen. Parts of the cycle store carbon for different lengths of time, and there are many processes that move carbon in and out of the stores. In the Calvin cycle, the ATP and NADPH formed during light reaction drive the reaction and convert 6 molecules of carbon dioxide into one sugar molecule or glucose. In general, the short-term carbon cycle encompasses photosynthesis, respiration, and predator-prey transfer of carbon. Carbon is a chemical element vital to all living things and is present in many non-living things. Launch Interactive Printable Version. Carbon dioxide produced during respiration is one of the reactants plants need to perform photosynthesis. The atmosphere is 20.9% oxygen by volume, which equates to a total of roughly 34 10 18 mol of oxygen. A biogeochemical cycle (or more generally a cycle of matter) is the pathway by which a chemical substance cycles (is turned over or moves through) the biotic and the abiotic compartments of Earth.The biotic compartment is the biosphere and the abiotic compartments are the atmosphere, hydrosphere and lithosphere.There are biogeochemical cycles for chemical elements, such as The slowest part of the cycle involves carbon that resides in sedimentary rocks, where most of Earths carbon is stored. Carbon is a chemical element that is an essential part of all living organisms. Carbon is also present in soil (lithosphere) as fossil fuels. Carbon dioxide (CO 2) is the primary greenhouse gas emitted through human activities.In 2020, CO 2 accounted for about 79% of all U.S. greenhouse gas emissions from human activities. This activity will teach students about the carbon cycle and why it is important to life on Earth.
