The Carbon Cycle
636
Conclusion
The Carbon Cycle consists of six processes that result in the exchange and recycling of carbon atoms.There are two carbon cycles: the fast carbon cycle, and the slow cycle. The processes that occur throughout the Carbon Cycle are photosynthesis, respiration, exchange, sedimentation and burial, extraction, and combustion. Each step in the carbon cycle either receives carbon dioxide or releases it.
Respiration
Photosynthesis
Most of the Carbon consumed by animals is released in the form of Carbon Dioxide (CO2). This feeds Carbon back into the cycle.
The Carbon Cycle in the ocean.
Carbon enters the atmosphere as carbon dioxide from respiration(breathing) or combustion(burning). Carbon Dioxide is absorbed by producers, or plants, to make carbohydrates during Photosynthesis. The reaction that occurs results in oxygen being released by the plants. Consumers then feed on the plants, retaining the Carbon they hold and passing Carbon along the food chain.
Exchange
A large amount of carbon is exchanged between the atmosphere and the ocean. Carbon cycling has to maintain a steady state between the earth and atmosphere.
Extraction
Human extraction of fossil fuels brings carbon to Earth's surface, where it can be combusted.
Combustion
The Carbon Cycle
Combustion converts fossil fuels and plant material into carbon dioxide.
The Carbon Cycle is a complex series of processes through which all of the carbon atoms in existence rotate.
Basic Carbon Cycle
There are two categories of the carbon cycle:
-Fast- living organisms
-Slow-carbon held in rocks, soils, or materials we use as fossil fuels
Sedimentation and burial.
- Sedimentation is a slow process; the small amounts of calcium carbonate sediment formed each year have accumulated over millions of years to produce the largest carbon pool in the 'Slow' Carbon Cycle.
Processes of the Carbon Cycle.
The Carbon Cycle is driven by six processes:
- Photosynthesis
- Respiration
- Exchange
- Sedimentation and burial
- Extraction
- Combustion
