fast carbon cycle

• Where does carbon circulate more rapidly?

  Atmosphere

  Oceans

  Living organisms (biosphere)

  Soils
• How much faster is the cycles in the FCC compared to the SCC?

  10 to 1000 times faster
• What are the key components of the fast cycle in the oceans ?

  Land plants and microscopic phytoplankton
• what processes make up the fast carbon cycle?

  Photosynthesis, respiration, decomposition, and carbon exchange
• Where does carbon exchange also occur?

  Between the atmosphere and the oceans.

  Atmospheric CO2 dissolves into oceans while the oceans ventilate this back to the atmosphere.

  Through this exchange individual carbon atoms are stored (by natural sequestration) for about 350 years
