| nitrogen cycle | cycle in which a gas in the air is fixed into a form that plants can use |
| evaporation | water turning into water vapor |
| water cycle | cycle in which water moves through the environment |
| condensation | water vapor turning into water |
| carbon-oxygen cycle | cycle in which plants turn gas in air into oxygen |
| respiration | process of releasing energy from food |
| transpiration | plants losing water through their stomato |
| precipitation | water falling from clouds |
| combustion | burning |
| oxygen | what plants release in photosynthesis |
| carbon dioxide | what animals release during respiration |
| nitrates | plants use these to make proteins |
| decay | the process tha tbacteria and fungi break down a dead organism's tissues and use some of the carbon as food |
| lightning | fixes a small amount of nitrogen |
| ammonia | a usable form of nitrogen that bacteria use in the nitrogen cycle |
| clouds | this is what forms when cold air causes water vapor to condense |
| burning fuels | one example of how carbon dioxide is produced |
| decayed organisms | this is what petroleum is made from |
| increase | if a forest was chipped down, what would happen to the carbon dioxide levels? |
| decrease | how would planitn gmore trees and riding a bike instead of driving affect the carbon dioxide levels? |
| bacteria | fix most of the nitro |
