Across
  1. 2. the part of a cell where photosynthesis happens
  2. 5. all the living and nonliving things interacting in a particular area
  3. 6. When there is _____________carbon (in the form of carbon dioxide) in abiotic matter, less carbon is available to producers for making energy storage molecules.
  4. 7. type of matter that makes up the nonliving parts of an ecosystem, such as air, water, and rocks
  5. 9. Carbon is part of carbon ___________, which is abiotic matter. Carbon is also part of energy storage molecules, which are biotic matter.
  6. 11. a type of energy storage molecule that organisms can use to release energy, and that is made of carbon, hydrogen, and oxygen atoms
  7. 12. an organism that makes its own food
  8. 13. When there is _____________carbon (in the form of carbon dioxide) in abiotic matter, more carbon is available to producers for making energy storage molecules.
  9. 15. If one part of a system ________________, this affects the rest of the system.
  10. 16. living things, such as plants, animals, and bacteria
  11. 17. a set of interacting parts forming a complex whole
  12. 18. When there is more sunlight, producers can make ______________energy storage molecules from the carbon in carbon dioxide.
Down
  1. 1. type of matter that makes up the living and dead organisms in an ecosystem
  2. 3. 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. 4. When there is _____________sunlight, producers cannot make as many energy storage molecules from the carbon in carbon dioxide.
  4. 8. During the process of __________________________, producers make energy storage molecules, using carbon from carbon dioxide and energy from sunlight. This moves carbon from abiotic to biotic matter.
  5. 10. an organism that gets energy storage molecules (such as glucose) by breaking down dead matter
  6. 14. the ability to make things move or change
  7. 15. an organism that needs to eat in order to get energy storage molecules (such as starch and fat)
