Photosynthesis and Cellular Respiration
Across
- 3. fuels that are produced from plant or animal matter
- 6. equation symbolic representation of a chemical reaction (2 wds.)
- 7. place in plant cells where photosynthesis takes place
- 9. the process by which producers use energy from the sun to make sugar
- 10. that which occupies space and has mass
- 12. place where a significant portion of cellular respiration takes place
- 13. process organisms use to release energy from sugars in the absence of oxygen
- 14. a measure of the rate of conversion of the sun's energy into matter by the producers in an ecosystem
Down
- 1. starting substances in a chemical reaction
- 2. process that uses oxygen to release the energy stored in food molecules (2 wds.)
- 4. microscopic photosynthetic organisms that live near the sunlit surface of nearly all freshwater and saltwater environments.
