  1. Carbon
    • element
    • found in all organisms=organic material
    • found in proteins, lipids, carbohydrates, and vitamins=organic compounds
    • CO2 is not an organic substance
  2. Word equation of Photosynthesis
    Carbon Dioxide + Water --> Sunlight + Chlorophyll --> Glucose + Oxygen
  3. Chemical Equation of Photosynthesis
    6CO2 + 6H2O -> Sunlight+Chlorophyll -> C6H12O6 + 6O2
  4. Glucose
    Food/Chemical energy
  5. What can do photosynthesis?
  6. What does photosynthesis do?
  7. Respiration
    break down of glucose to release energy
  8. Word Equation of Respiration
    oxygen + glucose --> carbon dioxide + water + energy
  9. Chemical Equation of Respiration
    6O2 + C6H12O6 --> 6CO2 +6H2O + energy
  10. Decomposition
    dead organic matter is broken down by organisms called decomposers (bacteria + fungi)
  11. How is glucose is broken down?
    By the decomposers in the process of respiration.
  12. Fossilisation
    dead organic matter can't decompose (lack of O2) over millions of years it forms into fossil fuels (oil, coal, gas)
  13. Combustion
    burning of fossil fuels
  14. What do fossil fuels contain?
  15. Word Equation of Combustion
    (fossil) fuel + oxygen --> carbon dioxide + water + energy
  16. Nutrition
    taking in food (containing C = glucose, sucrose, carbohydrates, fats, proteins)
  17. organic
    • living/dead organisms
    • contains carbon
