5. main type of sugar in the blood and is the major source of energy for the body's cells.
6. the regions of the surface, atmosphere, and hydrosphere of the earth (or analogous parts of other planets) occupied by living organisms.
9. a colorless, odorless gas produced by burning carbon and organic compounds and by respiration. It is naturally present in air (about 0.03 percent) and is absorbed by plants in photosynthesis.
11. Living
12. a molecule containing a very large number of atoms, such as a protein, nucleic acid, or synthetic polymer.
15. The green pigment found in the chloroplasts of higher plants and in cells of photosynthetic microorganisms
17. O2

20. the burning of fossil fuels
22. clearing, and removal of rainforest or related ecosystems

2. a gas that contributes to the greenhouse effect by absorbing infrared radiation, e.g., carbon dioxide and chlorofluorocarbons.
4. the envelope of gases surrounding the earth or another planet.
7. the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.

13. the ability to be maintained at a certain rate or level.
14. a series of actions or steps taken in order to achieve a particular end.
16. organic compound made of nothing more than carbons and hydrogens
