GEOG 1001 Midterm 3 Study Questions Exam will be on Tuesday, November 16th, 2010 at 11a – 12:15p in Hale 270 Note: The questions on this document only serve as a study guide. This guide is in no way intended be an example of the test, nor is it all inclusive of possible topics that may be covered on the test. It is only a resource to aid in studying.

Give the species to species interactions for the following scenarios: a. A pica eating grass b. A plant with nitrogen fixing bacteria in its roots c. A cheetah and a lion after the same zebra d. A flea on a dog e. A barnacle growing on a whale 2. Define autotroph and heterotroph. 3. What is Gross Primary Productivity (GPP)? Draw the diagram that relates GPP to Net Primary Productivity (NPP), and Net Ecosystem Productivity. Include what is lost with each step. 4. Diagram the nitrogen cycle with all the inputs, outputs, pools and fluxes between pools. Label everything. 5. In the Soil - Plant - Air Continuum, how is it possible for water to move up plants? What conditions must be true about the continuum for transpiration to occur? What is the anatomy that allows for water transport? How is transpiration regulated? 6. What is the role of producers and consumers in an ecosystem? 7. What is a limiting factor? How does it function to control the spatial distribution of plants and animals? 8. What are the principle abiotic components in terrestrial ecosystems? 9. What is ecosystem stability?10. Describe the vegetation, structure, and disturbances for each of the biomes discussed in class. What are the vegetation adaptations to each biome? 11. Why does the northern needle-leaf forest biome not exist in the Southern hemisphere, except in mountainous regions? 12. Describe how a generalist and a specialist relate to resource availability. 13. Explain the intermediate disturbance hypothesis. 14. List and explain the steps of the scientific method? 15. Explain how species are distributed across the globe. Think of the generalizations that can be made in terms of biodiversity at both, local and global scales. Focus on 1) Species area curve, 2) Global biodiversity patterns, 3) Latitudinal gradient of biodiversity, 4) NPP & Biodiversity, & 5) Intermediate Disturbance hypothesis Sample Questions: 1) Which if the following is not used to identify a community? a) Climate b) Patterns of interdependence c) Species present d) Trophic structure 2) Imagine the regions located near the subtropical high pressure center worldwide and their climate. Based on that, their NPP should be limited by a) Excess of sunlight b) Lack of rainfall c) Excess of cold temperatures d) All of the above 3) Which of the following would be true if 100 people could be fed from the grain produced on an acre of land? a) 200 people could be fed if the grain were first fed to the cows, which were then fed to the people. b) 100 people could be fed if the grain were first fed to the cows, which were then fed to the people. c) 50 people could be fed if the grain were first fed to the cows, which were then fed to the people. d) 10 people could be fed if the grain were first fed to the cows, which were then fed to the people. 4) The main difference between food chains and food webs is a) Food chains are more realistic and food webs are more complex. b) Food webs are more realistic and food chains are simpler. c) Food chains are more unrealistic and food webs are more complex. d) Food webs are more unrealistic and food chains are simpler.
