Exam 10: Population Dynamics

Refer to the figures. Figure 1 Figure 2 -What happened to the population between time 10 and 11? Based on the data prior to this point, what type of event most likely caused the change in the population size seen at that time? What additional data would you need to determine the underlying cause of the event?

Which of the following is not an observed pattern of population growth observed in nature?

Which of the following helped the Black Sea recover during the 1990s?

A population of wolves predates a population of moose on Isle Royale, Michigan, where there are fewer wolves than moose to start. The wolves prey on the moose and eat well, allowing them to have abundant offspring. However, as the wolf population rises, the moose population drops, and over time, the wolf population begins to drop also because of the reduced availability of resources. As the wolf population drops, moose are able to better survive and reproduce, causing the moose population to rise. With this abundance of moose, the wolf population is able to rebound until their population exceeds the moose population's ability to support the number of wolves. Which population dynamic does this series of oscillations represent?

Which of the following would be an example of genetic drift?

Assuming that their average population growth rates and all other factors are equal, which population would most likely be at risk for extinction?

Which equation best describes the pattern of population dynamics of the sheep in Tasmania from their introduction to the present day?

Eutrophication occurs when
