Biosphere

• Fluxes into biosphere


  -photosynthesis (atmosphere and hydrosphere)
• Fluxes out of biosphere


  -respiration (atmosphere and hydrosphere)

  -burial of sediment (lithosphere)
• Stores of carbon in the biosphere

  Primary producers (plants)

  Animals consuming plants and other animals
• How do plants move the carbons


  plants use solar energy to change water and CO2 into carbohydrates
• co2 around the atmosphere

  1,000 times more CO2 is taken out of the atmosphere that is released into it
• Carbon sequestering


  chemical move from one store to another
• Example of carbon sequestration


  Photosynthesis

  -carbon from atmosphere into carbohydrates (energy)
• what organisms use carbon sequestration

  Plants, animals, soils, bacteria, fungi
• Photosynthesis equation


  6CO2 + 6H2O ------> C6H12O6 + 6O2
• how much carbon do plants and the soil store?

  Plants- 550 PgC

  Soil- 1950 PgC
• Decomposer


  An organism that breaks down wastes and dead organisms

  -co2 is released during decomposition
• Detritivores


  consume organic material for their own nutrients, eat dead things
• job of decomposes and detritivores


  breakdown dead organic material adding nutrients into the soil
• Carboniferous Period (358-299 Mya)


  the only know time coal was produced

  -90% of all our coal
