Carbon cycle - definition of carbon cycle by The Free.
Carbon cycle definition, the circulation of carbon atoms in the biosphere as a result of photosynthetic conversion of carbon dioxide into complex organic compounds by plants, which are consumed by other organisms: the carbon returns to the atmosphere in the form of carbon dioxide as a result of respiration, decay by fungi, bacteria, etc., and combustion of fossil fuels.
In Part B: Students get a broader introduction to the carbon cycle by using an interactive visualization that highlights the major carbon reservoirs and processes in the larger, more complex global carbon cycle. They are able to see that the time scales of geosphere processes (thousands to millions of years) are much longer than time scales of biosphere processes (minutes to hundreds of years).
On our dynamic planet, carbon is able to move from one of these realms to another as a part of the carbon cycle. Carbon moves from the atmosphere to plants. In the atmosphere, carbon is attached to oxygen in a gas called carbon dioxide (CO 2). Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth. Carbon moves from plants.
Biosphere - Biosphere - The carbon cycle: Life is built on the conversion of carbon dioxide into the carbon-based organic compounds of living organisms. The carbon cycle illustrates the central importance of carbon in the biosphere. Different paths of the carbon cycle recycle the element at varying rates. The slowest part of the cycle involves carbon that resides in sedimentary rocks, where.
Changes in the Carbon Cycle 'Left unperturbed, the fast and slow carbon cycles maintain a relatively steady concentration of carbon in the atmosphere, land, plants, and ocean. But when anything changes the amount of carbon in one reservoir, the effect ripples through the others.; Effects of Changing the Carbon Cycle 'It is significant that so much carbon dioxide stays in the atmosphere.
The carbon cycle generally consists of carbon movement through the atmosphere, biospheres, ocean, and geosphere, but the deep carbon cycle between the mantle and crust of the geosphere is not as well understood as the other parts. Without the movement of tectonic plates and volcanic activity, carbon would eventually become trapped in the atmosphere. Scientists believe the quantity of carbon.

Carbon and the Global Carbon Cycle. Carbon is a ubiquitous element on Earth. Most of the Earth’s carbon is stored in rocks, but this carbon is essentially inert on the 100’s to 1000’s year timescales of interest.
