Study Guide

100 points

42 multiple choice

4 extended response questions

1. Contrast ecosystem, habitat, population, and community

2. Contrast carrying capacity and limiting factors

3. List density-dependent limiting factors

4. List density-independent limiting factors

5. Which graph cannot be sustained in nature: logistical or exponential? EXPLAIN in detail (using vocabulary) why.

6. What is the relationship between birth rate, death rate, and the size of a population? AND how does immigration and emigration affect the size of the population?

7. How is a parasitic relationship different from a traditional predator/prey relationship?

8. Contrast commensalism and mutualism

9. List three ways a population competes with itself

10. In detail (and using vocabulary), explain the history of human population growth over the past 10,000 years.

11. Population distribution is clumped, random, or uniform. Contrast each and provide an example organism for each.

12. Are highly competitive animals distributed in a uniform way? Why or why not.

13. How is zero population growth achieved? Could you show this in a mathematical equation?

14. Survivorship curves: graph the three survivorship curves and explain what is going on in each. Provide an example organism for each.

15. Deduct what may be occurring in each of the populations below (age structure diagrams): 16. Define taxonomy and state why it is important to ecologists

17. What is the name of Linnaeus’s two-name system of classification AND why did he create it?

18. Compare modern cladistics with the traditional (old) system of classifying organisms.

19. An ecologist says an organism’s growth will be exponential. What is this ecologist assuming about the organisms resources?

20. The same ecologist says an organism’s growth is logistical. What is he assuming about the organisms resources?

21. Construct a cladogram that contains five different organisms. Hypothesis the evolutionary history of the five by using your cladogram to guide your hypothesis.
