Chapter Objectives
1. Compare and contrast the major types of
species interactions.
2. Characterize feeding relationships and
energy flow, using them to construct trophic
levels and food webs.
3. Distinguish characteristics of a keystone
species.
From the Reading
1.
Identify eight types of
species interactions and
summarize their effects on
species.
2. Define competition.
Distinguish between
intraspecific and interspecific
competition.
3. Describe competitive
exclusion and provide an
example.
savannas
secondary succession
succession
symbiosis
temperate deciduous forest
temperate grasslands
temperate rainforest
trophic levels
tropical dry forest
tropical rainforest
tundra
4. Characterize the process of succession and
the debate over the nature of communities.
5. Perceive and predict the potential impacts of
invasive species in communities.
6. Explain the goals and methods of ecological
restoration.
7. Describe and illustrate the terrestrial
biomes of the world.
4. Describe species coexistence.
How does species coexistence
differ from competitive
exclusion?
5. Distinguish between
fundamental and realized
niche. Provide an example that
demonstrates both for a
single species.
6. Define resource partitioning
and provide an example.
7. Define mutualism and provide
an example.
8. Define symbiosis and provide
an example.
9. Define commensalism and
provide examples of each.
10. Define trophic level.
11. Identify and describe
producers.
12. Identify and describe
consumers. Distinguish among
primary, secondary, and
tertiary consumers.
13. Relate herbivores,
carnivores, and omnivores to
trophic levels. Give specific
examples.
14. Compare and contrast
detritivore and decomposer.
15. What is the relationship
between energy transfer and
trophic levels.
16. What is the relationship
between biomass and trophic
levels.
17. What is the relationship
between number of organisms
and trophic levels.
18. Compare and contrast food
chain and food web.
19. Define keystone species and
describe its impact on a
community.
20. Identify and describe two
general ways in which
communities respond to
disturbances.
21. Define succession.
Distinguish between primary
and secondary succession.
22. Define pioneer species and
provide an example.
23. Describe a climax community.
24. Define ecological restoration
and provide an example
25. Define biomes. What two
factors most often define
biomes.
26. Describe the ten biomes
identified by the authors.
