Transcript

  • 1. Photosynthesis The Big Picture
  • 2. Carbon cycle
    • Process by which carbon moves from organic t inorganic compounds and back
    • Producers convert inorganic carbon (CO2) into organic carbon compounds (glucose)
    • Primary Consumers obtain organic compounds by eating producers
    • Secondary consumers obtain organic carbon by eating primary consumers
    • Cellular Respiration by producers and consumers return CO2 to atmosphere
  • 3.
    • In the natural carbon cycle, there are two main processes which occur
      • Photosynthesis
      • metabolism

  • 7.  
  • 8. Carbon in Ocean and Sediments
    • CO2 is slightly soluble
    • Can be absorbed into water
    • Some of the dissolved CO2 remains in the water, the warmer the water the less carbon dioxide remains in the water
    • Some CO2 is used by algae and phytoplankton through the process of photosynthesis 
    • Coral and shelled marine organisms take up CO2 from the water and convert it into calcium carbonate
      • When these organisms die pieces of shells/coral fall to ocean floor and make sediments
    • The carbonate sediments are constantly being formed and redissolved in the bottom of the ocean
    • Over long periods of time, the sediments may be raised up as dry land or into mountains
    • This type of sedimentary rock is called limestone
    • The carbonates can redissolve releasing carbon dioxide back to the air or water
  • 9.  
  • 10.  
  • 11. Humans and the Carbon Cycle
    • Combustion of any type of fossil fuel, which may include oil, coal, or natural gas
    • Fossil Fuels  formed thousands of years ago from plant or animal remains that were buried, compressed, and transformed into oil, coal, or natural gas
    • This carbon is said to be "fixed" in place and is essentially locked out of the natural carbon cycle
    • Humans intervene during by burning the fossil fuels
      • During combustion in the presence of O2, CO2 and water molecules are released into the atmosphere
  • 12. Photosynthesis and Global Climate
    • CO2 makes up 0.03 percent of Earth’s atmosphere
      • 300 parts per million
    • Greenhouse Effect
      • CO2 traps heat from sun in Earth’s atmosphere (otherwise it would escape into space)
      • Not a bad thing
      • Keeps world climate warm enough to sustain life
      • Keeps Earth 10% warmer than it would be without CO2
    • Currently CO2 in atmosphere is rising
      • 360 parts per million
    • Burning fossil fuels
    • Deforestation
    • Natural Causes
      • Photosynthesis
      • Cellular respiration
      • Decomposition
      • Volcanic eruptions
      • Ocean/limestone
    • Global Warming
      • Overall rise in Earth’s average temperature over a period of time
