(B)
(C)
(D)

5. 57.1 Using the following graph, give an explanation for the trend in both the solid and dashed lines including
peaks and drops.
6. 56.2 How is the competitive exclusion principle demonstrated in the paramecium experiment?
7. The following is a food web for a meadow habitat that occupies 25.6 km2. The primary producers’ biomass is
uniformly distributed throughout the habitat and totals 1,500 kg/km2.
Developers have approved a project that will permanently reduce the primary producers’ biomass by 50
percent and remove all rabbits and deer. What changes in the populations is expected as a result at the
completion of the project?
8. 55.6 Describe the interaction that occurs between the North American snowshoe hare and the Canada Lynx

9. 56.3 Describe how plants use chemical defenses against herbivores? How do monarchs take advantage of
these chemical defenses? And how do nonpoisonous species of butterflies take advantage of the monarch
defense system?

factors can regulate a population of microscopic
organisms growing in a large flask that had the
growth patterns in period 1 & period 2 as shown:
12. The diagram above shows the progression of ecological events after fire in a particular ecosystem.
