Notes The Carbon Cycle

(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

(5) Fossil Fuels

• Examples
• Coal
• Gas

• Store HUGE quantities of carbon inside the earth
  (until dug up).
• Release HUGE quantities of carbon dioxide when
  burned.

(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
