Transcript

  • 1. Carbon CycleCarbon Cycle
  • 2. Carbon CycleCarbon CycleFourth most abundant element in universeBuilding block of all living thingsMain Pathway– in and out of living matter
  • 3. Key TermsKey TermsCarbon Cycle- Circulation of carbonthrough ecosystemsCarbon- A non-metallic element found incoal, petroleum and natural gas. Majorcomponent of life.Soil Respiration- Carbohydrates areoxidized and returned to the air by soilmicroorganisms that decompose deadanimals
  • 4. Key Terms ContinuedAtmosphere- layer of gassesFossil Fuels- Carbon-rich fuel from ancientanimals and plantsPhotosynthesis- Energy (sun)+ Water+Carbon dioxide Carbohydrates+ OxygenCellular Respiration- Glucose+ OxygenCO2+ H20+ Energy (ATP)Decomposition- breakdown of matter bybacteria and fungi
  • 5. Biological Importance of CarbonBiological Importance of CarbonAll living organisms contain carbonCO2 is found in all living organismsPlants use carbon dioxide and water toform simple sugars (photosynthesis)
  • 6. Ecological Importance of CarbonEcological Importance of CarbonCarbon is needed for lifeCarbon dioxide is a greenhouse gasCarbon is necessary for life, but carbondioxide can be harmful
  • 7. Amount of CarbonAmount of Carbon0.032% in the lithosphere2 petagrams
  • 8. Carbon in the atmosphereCarbon in the atmosphereSmallest amount of carbonApproximately 750 petagrams
  • 9. BiosphereBiosphere540- 610 gigatons
  • 10. hydrosphere38,00-40,00 metric tons
