Part 2: Review of Biomes

1. TWO QUESTIONS: Which biome is characterized by permafrost? What is permafrost?

2. List two features (physical characteristics) of a tropical rain forest biome.

3. Describe two ways in which temperate deciduous forests and temperate grasslands are different.

4. What are the dominant vegetation types found in the boreal forest biome, or taiga?

Part 3: Nutrient Cycles

**Be sure to review the DIAGRAMS of each cycle! **

5. Describe the TWO ways in which nitrogen is converted from N2 in the atmosphere to usable nitrogen compounds in the soil. Be sure to use the key term for this conversion process.

6. Which organisms are primarily responsible for converting N2 gas into usable nitrogen compounds and the converting those compounds back into N2 gas?

7. What is the term (name) for the process by which the organisms in #6 convert usable nitrogen compounds back into N2 gas?

8. List the TWO primary reservoirs of phosphorous.

9. Once it enters an ecosystem, how does phosphorous move through the system?

10. List THREE ways that waterenters the atmosphere (as water vapor/gas).

11. Whatiscondensation?

12. What TWO things can happen to water after it seeps into the ground (via seepage)?

13. How does carbonenter the atmosphere as CO2? (List ALL the ways)

14. How is carbonremoved from the atmosphere?

15. What are the primary reservoirs of carbon?
