Test Yourself True or False
___ 1. Water that changes from a gas to a liquid is evaporating. ___ 2. Water that changes from a gas to a liquid is condensing. ___ 3. Water vapor can get into the atmosphere by evaporation and condensation. ___ 4. Transpiration is rain, snow, sleet, and hail. ___ 5. Precipitation is rain, snow, sleet, and hail. ___ 6. Carbon atoms are found in the atmosphere in a gas called water vapor. ___ 7. Carbon atoms are found in the atmosphere in a gas called carbon dioxide. ___ 8. Photosynthesis is the process in which plants use the sun’s energy to make carbon dioxide and water into glucose. ___ 9. Animals obtain their carbon by breathing in carbon dioxide. ___ 10. When animals eat, the molecules may be broken apart in the process called cellular respiration.

Test Yourself True or False
___ 11. Photosynthesis takes carbon dioxide out of the atmosphere. ___ 12. Decomposition takes carbon dioxide out of the atmosphere. ___ 13. Nitrogen is the most abundant gas in Earth’s atmosphere. ___ 14. Nitrogen gas in the atmosphere is taken in by plants and used for photosynthesis. ___ 15. Nitrogen gas in the atmosphere cannot be used by plants or animals. ___ 16. Some bacteria are able to change nitrogen gas into a different molecule that plants can use. ___ 17. Animals eat plants or other animals to get the nitrogen they need. ___ 18. Animals return nitrogen to bacteria. ___ 19. Most phosphorus is found in the atmosphere. ___ 20. The phosphorus cycle is the slowest cycle.

Test Yourself Matching
___ 1. precipitation ___ 2. condensation ___ 3. evaporation ___ 4. transpiration ___ 5. photosynthesis ___ 6. cellular respiration ___ 7. decomposition ___ 8. combustion ___ 9. nitrogen-fixing bacteria ___ 10. phosphorus breaks down glucose to provide carbon to animals when a liquid changes to a gas the release of water vapor from plants when a gas changes to a liquid the majority is found in rocks and soil takes carbon dioxide out of the atmosphere adds carbon dioxide at an increasing rate returns carbon to the soil and atmosphere change atmospheric nitrogen gas into a form that is usable by plants when liquid water falls back to Earth

Most phosphorus can be found in ___________, ___________, and __________.
5
Test Yourself Answer the Following
Draw and explain the water cycle. Explain what happens to the water vapor when it cools? What does it form? The process where water is lost from the leaves of plants to the atmosphere is called transpiration. What are examples of water loss from humans?
6
Test Yourself Answer the Following
List and explain the 3 ways carbon is released from living things into the environment. Explain how photosynthesis moves carbon from the environment into living things. Explain how carbon is taken from the environment and can be used by a living organism. Be sure to explain how a carbon atom can end up in a: plant animal
