Answer Sheet
1. Sugar
2. Respiration
3. Carbon dioxide (CO2)
4. Oxygen
5. Water
6. People give off CO2 when they breathe. Plants take in the CO2. They use carbon to make glucose (sugar) and the oxygen goes back
into the atmosphere and we breathe it in. The cycle starts again.
7. Fewer plants mean less oxygen and more carbon dioxide. This disturbs the balance of the nature cycle.
8. b. Photosynthesis
9. d. Oxygen
10. d. Bacterial action
11. a. Decomposer
12. b. Precipitation
