Matter & Energy in Ecosystems
Across
- 2. The ability to make things move or change
- 5. 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)
- 7. Matter that makes up the nonliving parts of an ecosystem, such as air, water, and rocks
- 8. A starting substance that is part of a chemical reaction
- 10. Something that is required for a process
- 11. A molecule made of carbon and oxygen atoms
- 13. A group of atoms joined together in a particular way
- 14. A type of atom (tiny piece) that makes up molecules such as carbon dioxide and energy storage molecules
- 15. An organism that can make its own energy storage molecules
- 17. The chemical reaction between oxygen and glucose that releases energy into cells
Down
- 1. An ending substance that is made during a chemical reaction
- 2. A molecule that organisms can use to release the energy they need to survive
- 3. All the living and nonliving things interacting in a particular area
- 4. Matter that makes up the living and dead organisms in an ecosystem
- 6. An organism that gets energy storage molecules (such as glucose) by breaking down dead matter
- 9. An organism that needs to eat in order to get energy storage molecules (such as starch and fat)
- 12. Something that results from a process
- 16. A closed ecosystem made by humans
