Answer

C. primary

Answer

D. invasive

Question 14

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?

Accepted Answer

The rise in biodiversity makes the ecosystem more sustainable.

Answer

The rise in biodiversity makes the ecosystem less sustainable.

Answer

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

Answer

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

Question 15

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?

Accepted Answer

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

Answer

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

Answer

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

Answer

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

Question 16

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

Accepted Answer

to maintain the diversity of the living environment

Answer

to prevent oak trees from reproducing too quickly

Answer

to cause the extinction of undesirable animal species

Answer

to provide more land for agricultural purposes

Question 17

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

Accepted Answer

B. It helps to keep the ecosystem balanced.

Answer

A. It introduces fewer new species of organisms.

Answer

C. It allows organisms to avoid competition.

Answer

D. It creates a constant state of change.

Question 18

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?

Accepted Answer

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

Answer

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

Answer

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

Answer

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