Matter and Energy in Ecosystems

3. a type of energy storage molecule.
4. an organism that needs to eat in order to get energy storage molecules.
12. a group of atoms joined together in particular way.
13. respiration the chemical reaction between oxygen and glucose that release energy into cells.
14. a type of energy storage molecule.
15. something that results from a process.
16. a set of interacting parts forming a complex whole.
19. matter that makes up the living and dead organisms in an ecosystem.
21. the tiny pieces that all matter-all the stuff in the world-is made of.
24. living things, such as plants, animals and bacteria.
25. dioxide a molecule made of carbon and oxygen atoms.
26. something that is required for a process.
27. storage molecule a molecule that organisms can use to release the energy they need to survive.

1. the ability to make things move or change
2. the process by which plants and other producers use energy from sunlight to change carbon dioxide and water into oxygen and glucose.
4. the part of cell where photosynthesis happens.
5. to link two or more things.
6. an ending substance that is made during a chemical reaction.
7. an organism that gets energy storage molecules (such as glucose) by breaking down dead matter.
8. that part of a cell where cellular respiration happens.
9. a molecule that organisms can use to release energy, and that is made of carbon, hydrogen, and oxygen atoms.
10. a type of atom (a tiny piece) that makes up molecules such as carbon dioxide and energy storage molecules.
11. a closed ecosystem made by humans.
17. a type of energy storage molecule made of many glucose molecules connected together.
18. all the living and nonliving things interacting in a particular area.
20. a starting substance that is part of chemical reaction.
22. matter that makes up the nonliving parts of an ecosystem, such as air, water, and rocks.
23. an organim that can make its own energy storage molecules (such as glucose)
