1. What do each of the following represent: a) ZPG ___________________________________ b) r _____________________________________ c) K _____________________________________ d) CFC's _________________________________ e) PCB____________________________________ f) Po ____________________________________ 2. Explain the following terms a) Competitive exclusion b) Gaia Hypothesis c) 1st and 2nd laws of thermodynamics d) biogeochmeical cycles 3. What is the difference between interspecific competition and intraspecific competition? 4. What are 3 typical kinds of population pyramids? (shapes for age pyramids) 5. Why is genetic diversity important for the maintenance of high yields? 6. What determines the amount of oxygen dissolved in water? 7. Water reaches its maximum density at 4 oC. What three effects does this property produce that are significant for aquatic biomes? 8. Why do changes in altitude and changes in latitude produce similar changes in biomes? 9. What are some differences between the windward and leeward side of a mountain? 10. What is a cold desert? 11. How do the biotic and abiotic factors work together to stabilize the tundra biome? 12. What is the difference between oligotrophic, eutrophic and mesotrophic bodies of water. 13. Why are saltmarshes and mangrove swamps essential to ocean biomes? 9. Describe 3 correlates of r selection and 3 correlates of K selection (3 marks) 10. Name and describe the three typical kinds of population pyramids (3 marks) 11. Describe and give an example of the cyclic changes in population sizes. (3 marks) For each of the following questions: Answer either A or B (not both because only the first will be corrected and given marks) 12. a) Explain the Gaia Hypothesis (2 marks). OR b) If a large area of a rainforest is cleared, it requires nearly 400 years to regenerate itself (2x the time required by a temperate forest). Explain. 13. a) Water reaches its maximum density at 4 oC. What three effects does this property produce that are significant for aquatic biomes? (3 marks) OR b) Describe 6 features or aspects about a biome found in Canada (0.5 marks for each feature) 14. a) Why are wetlands often called the "kidneys" of aquatic biomes? (2 marks) OR b) How do the biotic and abiotic factors work together to stabilize the tundra biome? 15. a) What are the reasons, effects and solutions to the O3 problem (3 marks) OR b) Describe the effects and solutions to the DDT problem 16. Describe in detail, one of the geochemical cycles (3 marks) OR Name and describe the 3 types of ecological pyramids. Which type of pyramid do ecologists direct most of their attention to? 17. Write a short essay (1-2 paragraphs) about 1 of the following topics: (5 marks: 0.5 marks per information point) a) Wildlife Management (ideas: what is it, why is it necessary, what factors must be taken into consideration to make it successful, examples of successful cases or current situations where it should be put into place, options for wildlife managers) OR b) Discuss the article "BIG FISH, LITTLE FISH" 9. Describe 3 correlates of r selection and 3 correlates of K selection (3 marks) 10. Name and describe the three typical kinds of population pyramids (3 marks) 11.
