Across
- 3. The release of CO2 into the atmosphere by the burning of fossil fuels
- 8. The process by which carbon dioxide is pulled from the atmosphere by autotrophs to make glucose
- 16. An organism that has to get its food by eating other organisms
- 17. The process by which water vapor is released into the atmosphere from the stomata of plants
- 18. Consists of two hydrogen atoms and one oxygen atom; is a reactant of photosynthesis and a product of cellular respiration
- 19. The primary carrier of usable energy in the cell; acts like a full battery

Down
- 1. The process by which glucose is broken down to release energy and give off carbon dioxide (2 words)
- 2. The place in the cell where cellular respiration occurs

- 10. The outputs, or things remaining after a reaction
- 11. The place in the cell where photosynthesis occurs
- 12. The changing of water from liquid to gas form, which moves water into the atmosphere
- 13. An organism that can make its own food
- 14. The pores on the underside of a leaf that take in and release carbon dioxide

- 21. How atoms are joined together in a molecule (2 words)
- 22. The changing of water from gas form to liquid form, and the way clouds are formed
- 25. One of the characteristics of life: The process by which organisms create, take in, and use energy
