One of the roles of ecological succession is to allow species with different adaptations to interact. Ecological succession occurs in stages, providing periods of

• A. overlap only for species that migrate.

• B. separation only for species that do not migrate.

• C. separation for all species.

• D. overlap for a variety of species.

What is one difference between primary and secondary succession?

• Primary succession is slow and secondary succession is rapid.

• Secondary succession begins on soil and primary succession begins on virtually lifeless areas

• Primary succession modifies the environment, and secondary succession does not.

• Secondary succession begins with lichens and primary succession begins with trees.

Which type of species is the first to occupy a bare site?

• pioneer

• successive

• primary

• invasive

The term “biodiversity” refers to

• The number and variety of species living on Earth.

• The number and variety of species that are considered renewable.

• The number and variety of species that live in an area.

In a woodland ecosystem, the number of species of microorganisms in the soil that do not harm plants increases. How does this rise in biodiversity affect the sustainability of the ecosystem?

• The rise in biodiversity makes the ecosystem less sustainable.

• The rise in biodiversity makes the ecosystem more sustainable.

• The rise in biodiversity does not change the sustainability of the ecosystem.

• The rise in biodiversity makes the ecosystem only temporarily less sustainable.

A forest is an ecosystem in which different species of trees, insects, shrubs, and animals interact. How would the sustainability of a forest ecosystem be affected if the biodiversity of the forest increased?

• The sustainability of the forest ecosystem would decrease because there would be more interactions between different species.

• The sustainability of the forest ecosystem would increase because there would be fewer interactions between different species

• The sustainability of the forest ecosystem would decrease because there would be fewer interactions between different species.

• The sustainability of the forest ecosystem would increase because there would be more interactions between different species.

Which of the following is the best reason to protect a section of an oak forest?

• to prevent oak trees from reproducing too quickly

• to cause the extinction of undesirable animal species

• to provide more land for agricultural purposes

• to maintain the diversity of the living environment

Sustainability is defined as the ability of an ecosystem to survive over time. How does biodiversity affect the sustainability of an ecosystem?

• It introduces fewer new species of organisms.

• It helps to keep the ecosystem balanced.

• It allows organisms to avoid competition.

• It creates a constant state of change.

Scientists collect data regarding Earth's surface temperature over the last 900,000 years using direct and indirect methods. If they construct a graph of this data, which statement best describes the graph?

• The graph would start low, and then curve upward significantly to show a rapid rise in average temperatures.

• The graph would have a fairly straight line with a sharp curve upward to show recent rising temperatures

• The graph would have both highs and lows to show the periods of warm and cool temperatures.

• The graph would show stable temperatures followed by a sharp curve down as temperatures cooled
