At which time after clear-cutting does the ecosystem exhibit the greatest species richness?

1

Which tree species grows best with full sunlight?

1

Four islands, A, B, C, and D, differ only in distance from the mainland, area, and species diversity. Which island would be predicted to have the highest species diversity?

1

A one-hectare pond is sampled in early September. The sample yields 1 small catfish as well as 17 benthic invertebrates that represent 10 species.

If the pond is resampled a year later, which of the following would best indicate that the pond had been adversely affected by adjacent development?

1

A one-hectare pond is sampled in early September. The sample yields 1 small catfish as well as 17 benthic invertebrates that represent 10 species.

Which of the following can be estimated from the sample for the invertebrates in the pond?

1

Which of the following is NOT an example of an adaptation to help organisms acquire energy from their environment?

1

In North America, native pollinators often increase the quantity and quality of crops of native plants that are insect-pollinated more effectively than European honeybees do. The most likely reason for the phenomenon is the native pollinators

1

Which type of ecosystem services are resources such as timber and medicine?

1

For which of the following reasons do small isolated islands have a greater rate of species extinction than larger, less isolated islands?

1

Small populations of animals, such as those typically found on islands, are prone to extinction because

The table below shows measurements of the beak size of a sample of ten ground finches on each of two islands in the Galápagos archipelago. The two islands are about ten kilometers apart, and all the birds are the same species. Given that beak size is genetically determined, which of the following hypotheses is the most likely explanation for the differences in data between the islands?

1

The diagrams above show the range of tolerance for soil moisture content for two different species of a terrestrial invertebrate: Species 1 and Species 2. The ranges represented are for each species where it occurs alone. Soil moisture content is a limiting factor for both species. If populations of both species are placed together in a new location, which of the following diagrams represents the most likely actual (realized) ranges of the species’ distribution of individuals with respect to soil moisture content after five generations?

1

Which of the following best shows the process of evolution?

1

Which of the following can be used to assess the biological diversity of an area?

1

Which of the following is most likely to be the direct result of a lack of genetic diversity in a food crop such as corn?

1

Which type of ecosystem service are tourism and spiritual experiences?

1

Which combination of factors would result in the highest biodiversity?

1

The abiotic conditions under which a species can survive and reproduce is

1

Which statement about ecological succession is correct?

1

Which sequence of secondary succession would be likely to occur in abandoned farmland in the eastern United States?

1

Which is NOT true regarding keystone species?

1

Which condition does NOT define the fundamental niche of a species?

1

A researcher collects samples of aquatic insects from a variety of streams, as shown in the table.

Which stream has the greatest species richness?

1

A researcher collects samples of aquatic insects from a variety of streams, as shown in the table.

Scientists often use aquatic insect communities as indicators of water quality. Streams that are polluted can have low species evenness, and can be dominated by pollutant-tolerant taxa like midges and black flies. Based on this information, which of the four streams is most likely to be polluted?

1

The consumption of mosquitoes by bats and the control of flooding provided by tropical forests in mountainous areas of Central America are examples of
