Across
  1. 1. A molecule that organisms can use to release energy, and that is made of carbon, hydrogen, and oxygen atoms
  2. 3. A set of interacting parts forming a complex whole
  3. 7. The part of a cell where cellular respiration happens
  4. 9. Matter that makes up the nonliving parts of an ecosystem, such as air, water, and rocks (2 words)
  5. 12. To link two or more things
  6. 13. A starting substance that is part of a chemical reaction
  7. 15. An ending substance that is made during a chemical reaction
  8. 16. Something that is required for a process
  9. 19. Matter that makes up the living and dead organisms in an ecosystem (2 words)
  10. 20. A type of atom (a tiny piece) that makes up molecules such as carbon dioxide and energy storage molecules
  11. 22. An organism that gets energy storage molecules (such as glucose) by breaking down dead matter
  12. 24. Living things, such as plants, animals, and bacteria
  13. 25. An organism that can make its own energy storage molecules (such as glucose)
  14. 26. The tiny pieces that all matter—all the stuff in the world—is made of
Down
  1. 2. An organism that needs to eat in order to get energy storage molecules (such as starch and fat)
  2. 4. A molecule made of carbon and oxygen atoms (2 words)
  3. 5. A type of energy storage molecule
  4. 6. A group of atoms joined together in a particular way
  5. 8. Something that results from a process
  6. 10. A molecule that organisms can use to release the energy needed to survive (3 words)
  7. 11. A type of energy storage molecule made of many glucose molecules connected together
  8. 14. The chemical reaction between oxygen and glucose that releases energy into cells (2 words)
  9. 15. 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)
  10. 17. All the living and nonliving things interacting in a particular area
  11. 18. A type of energy storage molecule
  12. 19. A closed ecosystem made by humans
  13. 21. The ability to make things move or change
  14. 23. The part of a cell where photosynthesis happens
