Matter & Energy in Ecosystems

2. the part of a cell where photosynthesis happens
4. a type of energy storage molecule made of many glucose molecules connected together
8. the part of a cell where cellular respiration happens
9. the nonliving parts of an ecosystem, such as air, water, and rocks
13. an organism that needs to eat in order to get energy storage molecules (such as starch and fat)
15. a molecule made of carbon and oxygen atoms
17. all the living and nonliving things interacting in a particular area
21. the chemical reaction between oxygen and glucose that releases energy into cells
23. a type of energy storage molecule
24. a type of energy storage molecule
25. to link two or more things
26. a closed ecosystem made by humans
27. a molecule that organisms can use to release energy, and that is made of carbon, hydrogen, and oxygen atoms

1. 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. a set of interacting parts forming a complex whole
5. an organism that gets energy storage molecules (such as glucose) by breaking down dead matter
6. living things, such as plants, animals, and bacteria
7. something that results from a process
8. a group of atoms joined together in a particular way
10. an organism that can make its own energy storage molecules (such as glucose)
11. a type of atom (a tiny piece) that makes up molecules such as carbon dioxide and energy storage molecules
12. a molecule that organisms can use to release the energy they need to survive
14. a starting substance that is part of a chemical reaction
16. something that is required for a process
18. the ability to make things move or change
19. an ending substance that is made during a chemical reaction
20. the living and dead organisms in an ecosystem
22. the tiny pieces that all matter—all the stuff in the world—is made of
