Matter, Energy, & Ecosystems
Across
- 3. 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)
- 6. a small part that is meant to show what the whole is like
- 9. the chemical reaction between oxygen and glucose that releases energy into cells
- 10. the part of a cell where photosynthesis happens
- 11. the ability to make things move or change
- 12. a substance, object, or organism that has mass (like weight) and volume (takes up space)
- 14. a population that eats organisms from another population
- 17. something that is required for a process
- 18. a group of the same type of organism living in the same area
- 19. a group of organisms of the same kind (in one or more populations) that do not reproduce with organisms from any other group
- 20. a model that shows that eats what in an ecosystem
- 24. a set of interacting parts forming a complex whole
- 25. when something stays mostly the same over time
- 26. a type of atom that makes up molecules such as carbon dioxide and energy storage molecules
- 28. the process of creating offspring
- 31. a type of energy storage molecule
- 32. matter that makes up the nonliving parts of an ecosystem, such as air, water, and rocks
- 33. a type of energy storage molecule
- 34. the part of a cell where cellular respiration happens
Down
- 1. a closed ecosystem made by humans
- 2. a molecule that organisms can use to release the energy they need to survive
- 4. a molecule that organisms can use to release energy, and that is made of carbon, hydrogen, and oxygen atoms
- 5. something that results from a process
- 6. a type of energy storage molecule made of many glucose molecules connected together
- 7. a population that is eaten by organisms form another population
- 8. an organism that gets energy storage molecules (such as glucose) by breaking down dead matter
- 13. a molecule made of carbon and oxygen atoms
- 15. an organism that can make it own energy storage molecules (such as glucose)
- 16. an organism that needs to eat in order to get energy storage molecules (such as starch and fat)
- 21. living things, such as plants, animals, and bacteria
- 22. matter that makes up the living and dead organisms in an ecosystem
- 23. all the living and nonliving things interacting in a particular area
- 27. an ending substance that is made during a chemical reaction
- 29. a scientist who studies the interactions of organisms with each other and their environment
- 30. a starting substance that is part of a chemical reaction
