  1. Notes: The Carbon Cycle

  2. (1) What is a Cycle? • Cycle: Continuous movement or transfer of something. • Cycling in Ecosystems: • All Matter (nutrients) continuously move between organisms and regions. • Energy continuously moves between organisms… • Not ALL energy is 100% recyclable • Some energy “lost” as heat  Increased Entropy/Disorder

  3. (2) Carbon • Type of element or atom • Common Compounds: • Carbon Dioxide (CO2) • Glucose (C6H12O6) • Methane (CH4) • Carbon Monoxide (CO)

  4. (3) Carbon & Photosynthesis • Carbon Dioxide Removed from… • Atmosphere or Hydrosphere • Glucose released into… • Hydrosphere, Geosphere, Biosphere

  5. (4) Carbon & Respiration • Glucose removed from… • Geosphere, Hydrosphere, Biosphere • Carbon Dioxide released into… • Atmosphere or Hydrosphere

  6. (5) Fossil Fuels • Examples: • Coal • Gas • Oil • Source: • Old, compressed, heated remains of organisms • Store HUGE quantities of carbon inside the earth (until dug up). • Release HUGE quantities of carbon dioxide when burned.

  7. (6) Carbonates • Bicarbonate: (HCO3) • Used as a buffer in organisms + water systems • Calcium Carbonate: (CaCO3) • Compound formed from the shell-remains of aquatic organisms • Found underground and in water systems
