Unit 2.1 and Unit 2.2 Test

Which of the following is an example of an ecosystem that provides ecosystem services including protection from hurricane storm surges?

An intact coastal wetland

Based on the information above, which of the following best describes Ecosystem C?

Its high genetic diversity indicates that Ecosystem C most likely has species that evolve quickly.

Based on the information above, which ecosystem would most likely recover the fastest from a natural disruption?

Ecosystem B

Based on the information above, which ecosystem most likely experienced a recent population bottleneck?

Ecosystem A, because its low genetic diversity could have resulted from an event that reduced the variation in the gene pool.

Which of the following statements about levels of biodiversity is correct?

A population with high genetic biodiversity is better able to respond to environmental stressors.

Which of the following would most likely result from the deforestation of large areas of tropical rain forests caused by slash-and-burn agriculture?

Increased global temperature because of the release of CO2

Which of the following ecosystem services are categorized as regulating?

Pollination, decomposition, and water purification

Which of the following economic consequences to a provisioning ecosystem service will most likely result from increased global warming?

Widespread crop failure, because of increased acid precipitation in agricultural areas

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.

Which of the following examples illustrates the community with the highest biodiversity?

Species	Number of individuals
A	10
B	10
C	10
D	10
E	10
