Matter and Energy

1. A set of interacting parts forming a complex whole
3. A group of atoms joined together
6. Matter that makes up the living and dead organisms in an ecosystem
10. All the living and nonliving things interacting in a particular area
13. The chemical reaction between oxygen and glucose that releases energy into cells
15. A type of energy storage molecule
18. Matter that makes up the nonliving parts of an ecosystem
19. Living things, such as plants, animals, and bacteria
22. An ending substance that is made during a chemical reaction
24. Something that is required for a process
25. A type of energy storage molecule made of many glucose molecules connected together
26. An organism that can make its own energy storage molecules
27. The part of a cell where photosynthesis happens
28. An organism that gets energy storage molecules by breaking down dead matter

2. A molecule that organisms can use to release the energy they need to survive
4. To link two or more things
5. The tiny pieces that all matter is made of
7. A type of atom that makes up the living and dead organisms in an ecosystem
8. A starting substance that is part of a chemical reaction
9. An organism that needs to eat in order to get energy storage molecules
11. The ability to make things move or change
12. A molecule made of carbon and oxygen atoms
14. The process by which plants and other producers use energy from sunlight to change carbon dioxide and water into oxygen and glucose
16. An ecosystem experiment in the 90's
17. A type of energy storage molecule
20. A molecule that organisms can use to release energy, made of carbon, hydrogen, and oxygen
21. The part of a cell where cellular respiration happens
23. Something that results from a process
