Question 10 of 21

1

Before it was banned in the United States in 1972, the pesticide DDT was used to treat wetlands where mosquitos breed. There, algae would accumulate DDT in their tissues. Small aquatic animals such as mayfly nymphs would eat the algae. Fish would eat the mayfly nymphs and osprey would eat the fish. Which tropic level would have the highest DDT levels?

  • remediation

Explanation

Question 12 of 21

1

Robert Paine studied sea stars in the intertidal zone along the northern Pacific coast. When he removed sea stars from a study area, their prey, two mussel species, increased exponentially. This crowded out other species, and the overall biodiversity of the community was greatly reduced. In this example, you would call the sea star a keystone species.

Select one of the following:

  • True
  • False

Explanation

Question 13 of 21

1

Species diversity is highest when ________.

Select one of the following:

  • species richness is low and relative abundance is unevenly distributed

  • species richness is high and relative abundance is unevenly distributed

  • species richness is high and relative abundance is evenly distributed

  • species richness is low and relative abundance is evenly distributed

Explanation

Question 14 of 21

1

Explanation

Question 15 of 21

  • primary

  • secondary

  • ecological

Explanation

Question 16 of 21

1

The emerald ash borer is an invasive insect species that has killed millions of ash trees since it was first identified as a threat in 2002. The U.S. Forest Service has a management plan that includes extensive surveys to detect new infestations, quarantines of materials from already infested forests, public education, chemical treatments, investigation of possible parasites that might attack the ash borer, and an investigation of cultural practices that might help reduce the threat. This control method is an example of biological control.
