A field is abandoned, and an invasive plant that can live in nutrient-poor soil moves into the field. If the land is later cleared of this invasive species and it is discovered that the soil has an abundance of nitrogen compounds, what conclusion can best be made?

• The plants used up all of the phosphorus and potassium and left the nitrogen behind.

• Primary succession always produces an abundance of nitrogen.

• Bacteria in soil and in root nodules converted free nitrogen into nitrogen compounds.

• The plants were able to produce nitrogen in their leaves.

How does the burning of fossil fuels contribute to the net increase in atmospheric carbon?

• Photosynthesis is reduced by virtue of increased smoke and haze.

• Carbon released by the burning is not in a form that can be readily absorbed by plants, leaving residual carbon in the atmosphere.

• Carbon that has been sequestered underground is added to the carbon cycling between the atmosphere and the biosphere.

• Carbon released by the burning is more easily absorbed in the atmosphere than that produced by natural means.

• 4000

• 8000

• 12,000

• 20,000

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

Which of the following biomes is best characterized as an area that forms the narrow band along the coast that experiences a range of environmental conditions (including daily changes in sunlight, temperature, and water) ?

• Open ocean

• Lakes

• Coral reefs

• Intertidal zones

Which of the following is a measure of the biodiversity of an ecosystem?

Which of the following correctly describes the disruption of an ecosystem service by an anthropogenic activity?

• Provisioning services are disrupted by increased combustion of fossil fuels, which leads to an increase in air pollution.

• Regulating services are disrupted by flash flooding from a hurricane, which decreases available food resources.

• Supporting services are disrupted by an earthquake that causes habitat destruction, which displaces plants and animals.

• Cultural services are disrupted by a tornado that causes the loss of acres of forest, which reduces the amount of harvestable timber.
