Question 1

1.

Wolves were reintroduced into Yellowstone National Park in 1995. In addition to tracking changes in the wolf population, scientists were interested in how the wolves would affect other parts of the Yellowstone ecosystem. In particular, they were interested in changes to the population of elk, the wolves’ primary prey. The graph below shows the population size of the wolf and elk populations over time.

Which of the following is a potential disadvantage of reintroducing wolves to Yellowstone?

The wolves are causing a trophic cascade that could further increase the number of beavers and tree species such as willows and aspens.

Wolves are extremely fast breeders and may become an invasive species if they get outside the park.

Wolves leaving the park may prey on livestock in grazing land outside the park.

The ecosystem could collapse because wolves were never in Yellowstone before 1995.

Question 2

2.

The shaded regions in the diagram below show where different species of warblers, a type of bird, hunt for insects in the same tree.

Which of the following interactions between the warbler species is shown in the diagram?

Parasitism

Resource partitioning

Commensalism

Intraspecific competition

Question 3

3.

In 1960, an invasive fly was introduced to the Galapagos islands.

To understand the relationship between the invasive fly and the tree finches that live on the island, researchers examined the mating success of two species of finches. Some finches had nests with flies and some did not. The data from the study are in the table.

Based on the table, which of the following claims about the relationship between the tree finch and the invasive fly is best supported?

The flies and finches have a commensal relationship; finches provide a home for the fly, but finches are not affected by the presence of the fly.

The flies and finches have a mutualistic relationship; the finch provides a home for the fly, and the fly helps the breeding success of the finch.

The flies and finches have a parasitic relationship; the finches provide a home for the fly, and the fly decreases the breeding success of the finches.

The flies and finches have a competitive relationship; the two species feed on the same food, and the finches are more successful at feeding than the flies are.
