This biome contains plants that are adapted to prevent water loss due to the low average rainfall

• Savanna

• Boreal forest

• Tropical rain forest

• Desert

The underlying subsoil of this biome is permafrost, which prevents both water draining through and deep-rooted plants from growing. Additionally, there is very little precipitation per year.

• Temperate grasslands

• Taiga

• Tropical rain forest

• Tundra

Which of the following is true of carbon as it cycles in nature?

• Carbon dioxide is released during photosynthesis.

• Carbon compounds rarely exist in the gaseous state.

• Carbon sinks include forests and oceans.

• The carbon dioxide concentration in the atmosphere is reduced by cutting trees.

Based on the diagram above, which process most directly results in the storage of carbon as coal and oil over millions of years?

• Photosynthesis

• Cellular respiration

• Decomposition

• Burning fossil fuels

The graph here best exemplifies

• the demographic transition

• sustained logarithmic growth

• competitive exclusion

• normal distribution

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.

Based upon the data presented in the graph, which of the following best identifies the highest wolf population size?

• 20

• 120

• 170

• 190

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.

Photosynthesis is the major source of which of the following gases in Earth’s atmosphere?

• CO₂

• H₂O

• O₂

• H₂

Exemplified by moss growing on a tree trunk in a forest

Nitrate ions and nitrite ions are converted into nitrous oxide and nitrogen gas (N₂)

• Nitrification

• Denitrification

• Assimilation

• Ammonification

• Nitrogen fixation
