Transcript of (1) What is a Cycle? Cycle: Continuous movement or transfer of something. Cycling in Ecosystems:...
(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
(2) Carbon• Type of element or atom
• Common Compounds:– Carbon Dioxide (CO2)
– Glucose (C6H12O6)
– Methane (CH4)
– Carbon Monoxide (CO)
(3) Carbon & Photosynthesis
• Carbon Dioxide Removed from…– Atmosphere or Hydrosphere
• Glucose released into…– Hydrosphere, Geosphere, Biosphere
(4) Carbon & Respiration
• Glucose removed from…– Geosphere, Hydrosphere, Biosphere
• Carbon Dioxide released into…– Atmosphere or Hydrosphere
(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.
(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
