Matter & Energy in Ecosystems

2. - a group of atoms joined together in a particular way
7. - the part of a cell where photosynthesis happens
10. - an organism that can make its own energy storage molecules
11. - a closed ecosystem made by humans
14. - the ability to make things move or change
16. - the process by which plants and other producers use energy from sunlight to change carbon dioxide wand water into oxygen and glucose
17. - a set of interacting parts forming a complex whole
18. - the tiny pieces that all matter—all the stuff in the world—is made of
20. dioxide - a molecule made of carbon and oxygen atoms
21. - the part of a cell where cellular respiration happens
22. - matter that makes up the living and dead organisms in an ecosystem
23. - an organism that needs to eat in order to get energy storage molecules
25. - an ending substance that is made during chemical reaction

1. - a molecule that organisms can use to release energy, and that is made of carbon, hydrogen, and oxygen atoms
3. respiration - the chemical reaction between oxygen and glucose that releases energy into cells
4. - a type of atom (a tiny piece) that makes up molecules such as carbon dioxide and energy storage molecules
5. - living things such as plates, animals, and bacteria
6. - an organism that gets energy Storage molecules
8. - Something that results from a process
9. - all the living and nonliving things interacting in a particular area
12. - something that is required for a process
13. - matter that makes up the nonliving parts of an ecosystem, such as air, water, and rocks
15. - a starting substance that is part of a chemical reaction
19. storage molecule - a Molecule that organisms can use to release the energy needed to survive
20. - to link two or more things
24. - a type of energy storage molecule made of many glucose molecules connected together
