Question

Which biome exists in the coldest and driest conditions in the Arctic Circle? A) Tropical rainforest B) Savanna C) Deciduous forest D) Northern coniferous forest E) Tundra A clear, high mountain lake with few nutrients but a high oxygen concentration would be considered A) Highly productive B) Oligotrophic C) Autotrophic D) Dense with algae E) Eutrophic Introduced species can have detrimental effects on biological communities by A) Preying on native species B) Competing with native species for food or light C) Displacing native species D) Competing with native species for breeding/nesting habitat E) All of the above Within the Front Range foothills, stretches of natural habitat are interrupted with the neighborhood, creating a mosaic of natural and developed areas. This is an example of A) Introduced species B) Overexploitation C) Pollution D) Disruption E) Habitat fragmentation Which type of biome is characterized by grasslands and occasional trees bordering tropical rainforests? A) Desert B) Savanna C) Taiga D) Temperate grasslands E) Tundra After whale populations dropped, killed whale predated otters more frequently, otters ate fewer sea urchins, and the urchin population exploded and impacted kelp forests. This process is an example of A) Introduced species B) Disruption C) Overexploitation D) Pollution E) Habitat fragmentation What causes seasonality on Earth? A) Global wind patterns B) Global air circulation C) Ocean currents D) Earth's variable proximity to the sun E) The tilt of Earth's axis During the Pleistocene, when Paleoindians moved into North America, what was the primary cause of extinction? A) Habitat fragmentation B) Disruption C) Clearcutting forests D) Overexploitation E) Pollution
