Warm-Up #6: 10/11/09 Answers only – show your math! 1. Scientists involved in a field study of a biome produced the graph above. The line represents temperature and the bars represent precipitation. Which of the following is a valid conclusion about the biome? A.The biome is a rainforest. B.The annual variation in temperature (from high to low) is about 25°C. C.The biome receives the same amount of rainfall each month. D.The biome has little plant life. 2. About 15 m of topsoil covers the eastern plains of the United States. If topsoil forms at the rate of 2.5 cm per 500 years, how long did it take for the 15 m of topsoil to form?

Warm-Up #7: 10/12/09 1. What processes are involved in releasing carbon into the atmosphere? 2. If respiration is the opposite of photosynthesis, what is the molecular equation for respiration?

Warm-Up 10: 10/16/09 Answer in a complete sentence. Why is carbon, nitrogen, and water important for use to live?

Warm-Up 8: 10/14/09 Copy and Answer - True or False: 1.Plants get energy from the waste products of animals. 2.Animals get energy from the plants that the animals eat. 3. Bacteria fix nitrogen into forms that plants can use. 4. The burning of fossil fuels is caused by decomposition.

Warm-Up 9: 10/15/09 All organisms need nitrogen to build cells and cell parts. Nitrogen exists in the atmosphere as a gas, but most organisms cannot use nitrogen in this form. At what stage in the nitrogen cycle is nitrogen turned into a form that plants can use? How do animals get nitrogen?
