  1. Autotroph
    organism that makes its own food
  2. Photosynthesis
    process by which plants use the sun's energy to convert water and carbon dioxide into sugars
  3. Producer
    organism that makes its own food (autotroph) and produces organic molecules that serve as food for other organisms in its ecosystem
  4. Heterotroph
    organism that obtains food by eating other organisms
  5. Consumer
    organism that obtains food by eating producers (autotrophs) or other consumers
  6. Cellular Respiration
    chemical process that uses oxygen to convert chemical energy stored in organic molecules into ATP (adenosine triphosphate)
  7. Kinetic Energy
    energy of motion
  8. Potential Energy
    energy stored due to an object's position or arrangement
  9. Thermal Energy
    total amount of energy associated with the random movement of atoms and molecules in a sample of matter
  10. Chemical Energy
    potential to perform work due to the arrangement of atoms within molecules
  11. Calorie
    amount of energy required to raise the temperature of 1 g of water 1°C
  12. ATP
    (adenosine triphosphate) main energy source that cells use for most of their work
  13. Aerobic
    requiring oxygen
  14. Electron Transport Chain
    sequence of electron carrier molecules that transfer electrons and release energy during cellular respiration
  15. Metabolism
    all of a cell's chemical processes
  16. Glycolysis
    the splitting in half of a glucose molecule; the first stage of cellular respiration and fermentation
  17. Krebs cycle
    stage of cellular respiration that finishes the breakdown of pyruvic acid molecules to carbon dioxide, releasing energy
  18. ATP synthase
    protein structure in cell mitochondria that uses energy from H+ ions to convert ADP to ATP
  19. Fermentation
    cellular process of making ATP without oxygen
  20. Anaerobic
    without oxygen
