  1. 3. the ability to make things move or change
  2. 5. the process by which plants and other producers use energy from sunlight to change carbon dioxide and water into oxygen and glucose (an energy storage molecule)
  3. 13. living things, such as plants, animals, and bacteria
  4. 14. a molecule made of carbon and oxygen atoms
  5. 15. a group of atoms joined together in a particular way
  6. 16. a molecule that organisms can use to release energy, and that is made of carbon, hydrogen, and oxygen atoms
  7. 17. an organism that needs to eat in order to get energy storage molecules (such as starch and fat)
  8. 19. an organism that gets energy storage molecules (such as glucose) by breaking down dead matter
  9. 20. matter that makes up the nonliving parts of an ecosystem, such as air, water, and rocks
  10. 21. the part of a cell where cellular respiration happens
Down
  1. 1. all the living and nonliving things interacting in a particular area
  2. 2. a molecule that organisms can use to release the energy they need to survive
  3. 4. a set of interacting parts forming a complex whole
  4. 6. a type of energy storage molecule made of many glucose molecules connected together
  5. 7. the part of a cell where photosynthesis happens
  6. 8. an organism that can make its own energy storage molecules (such as glucose)
  7. 9. a closed ecosystem made by humans
  8. 10. a type of atom (a tiny piece) that makes up molecules such as carbon dioxide and energy storage molecules
  9. 11. the tiny pieces that all matter—all the stuff in the world—is made of
  10. 12. the chemical reaction between oxygen and glucose that releases energy into cells
  11. 18. matter that makes up the living and dead organisms in an ecosystem
