Chapter 40 Populations
1. Distinguish between species distribution and species dispersal. What factors can contribute to
each?
2. Distinguish between biotic an abiotic factors and give several examples of each
3. How might #2 above contribute to #1 above?
40.4
4. Describe 3 different patterns of dispersion
5. What type of information can a life table convey?
6. What do survivorship curves show and what is the difference between types I, II, and III?
40.5
7. What equation can ecologists use to represent population growth. Be able to explain each term
in the equation
8. Describe (verbally) what is happening to a population undergoing exponential population
growth. Use an equation to describe this.
9. Describe what is meant by carrying capacity and how this results in logistic growth.
40.6
10. What is meant in ecology by “life history” and relate this to trade-offs.
11. Contrast species that are r-selected to those that are K-selected. Give specific examples.
12. What is Q and how does this relate to density-independent and density-dependent birth and
death rates.
13. Describe several examples of regulating a population via density-dependent population
regulation
Chapter 41 communities
41.1
14. Describe several interactions within a community that fall into the following categories (-/-), (/+), (+/+ and +/0)
15. Give several examples of mechanisms organisms can use to escape predation.
41.2
16. What are the components of species diversity?
17. Describe the trophic structure within a community and the relationship that a keystone species
has within it.
41.3
18. Describe what is meant by succession and what differentiates between primary and secondary
succession.
Chapter 42 Ecosystems
42.1
19. Describe the difference between energy flow and chemical cycling in an ecosystem
42.2
20. What is meant by production within an ecosystem
21. What is net primary production and how is it calculated?
22. How is net ecosystem production calculated?
23. What are limiting factors and give some examples
42.3
24. Describe an energy pyramid and what it shows.
