Document Summary
Fluxes: photosynthesis & chemosynthesis (ch4, respiration (consumption & decomposition, sedimentation, uplift & erosion, dissolution, energy, solar energy (photosynthesis, chemical energy (chemosynthesis, consumers & decomposers get their energy by oxidizing organic carbon (cellular respiration) Human impacts on the carbon cycle: burning fossil fuels, moves carbon out of a stable reservoir & into the atmosphere, deforestation, decreases the amount of carbon pulled out of the atmosphere. Soil disruption: unsustainable agricultural practices, tilling of soil ->very rapid decomposition & oxidation of soil organic matter. Industrial n fixation intera(cid:272)tions with the c cycle: potential to increase photosynthesis - pulls carbon out of the atmosphere, ha(cid:271)er bos(cid:272)h process in also extremely energy (fossil fuel) intensive. Industrial (haberbosch: uptake or assimilation, decomposition, mineralization, energy, nitrogen fixation requires a high input of energy, electricity (lightning, petroleum (industrial) Solar energy (biological: nitrification & denitrification are ways that bacteria harvest energy.
