APES Unit 2 Biodiversity
which of the following best describes Ecosystem C?
Its low habitat diversity indicated that Ecosystem C most likely has a low number of specialist species and few species that utilize large territories
Which of the following best describes the pattern in the atmospheric CO2 concentration data over the past 200,000 years?
The concentration of CO2 fluctuated between 150 ppm and 250 ppm until recently when the concentration rose exponentially
Which of the following is the source of energy driving the circulation pattern labeled C in the diagram?
Solar radiation
Which of the following economic consequences to a provisioning ecosystem service will most likely result form increased global warming?
The collapse of local fisheries, because of the damage to coral reefs from ocean acidification
Based on the graph above, which of the following years postdisturbance did sweetgum experience the greatest biomass?
50
Which of the following is an example of an ecosystem that provides ecosystem services including protection from hurricane storm surges?
An intact coastal wetlad
Based on the theory of island biogeography, which of the following islands would most likely have the highest number of species living on it?
An island 30 hectares in size that is 10 kilometers off the coast of the mainland
An island off the coast of Africa contains a larger percentage of specialist species than generalist species. Which of the following describes the most immediate effect if an invasive generalist species is introduced to the island?
As competition for resources increases the population size of the island specialist species will decrease
Which of the following best describes the trends in atmospheric CO2 concentration and Antarctic temperature over the past 800,000 years?
Atmospheric Co2 concentration and Antarctic temperature are directly correlated over the past 800,000 years
Which of the following is a biome found at 30° N and 30° S as seen in the diagram?
Deserts
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
A team of ecologists are studying four different ecosystems with varying levels of biodiversity. The ecologists categorize the different levels of biodiversity for the four ecosystems as shown in the table below. Which ecosystem would most likely recover the fastest from a natural disruption?
Ecosystem B
Which of the following best explains why the shaded area receives more snowfall than the other parts of New York, Pennsylvania, and Ohio?
Moisture picked up from the warmer water in the Great Lakes is deposited as snow downwind.
What describes the stratosphere?
The ozone layer, temp increases with height, atmosphere thins with height
Researchers examined the effect of industrialization and increased pollution (soot) in London on the coloration in a single species of moths. Birds prey on the moths that are easily visible on trees. The researchers observed moths on tree trunks and recorded their body color. The percentage of moths with light colored bodies and the percentage of moths with dark bodies is shown on the graph above. Which of the following best describes the change in the population of moths as a result of industrialization?
The percentage of dark colored moths increased in population and percentage of light colored moths decreased in population
Which of the following best explains why City B regularly receives less precipitation than City A?
The rain shadow effect causes City B to be drier because the mountain blocks precipitation from reaching the city.
Which of the following best describes the change in Antarctic temperature from about 440,000 years ago to about 340,000 years ago?
The temperature increases by about 12C and then decreases by about 12C
In the desert regions of the southwestern United States, daily high and low temperatures will frequently fluctuate by 40°F (33°C) or more. Which statement below best explains the large variation in temperature?
There are no bordering oceans or large bodies of water to provide a stabilizing humidity to the air.
Based on the graph above, which of the following tree species would be the predominant species found during the intermediate stage of succession?
Tulip poplar
Which of the following causes the air to rise high into the atmosphere in the areas labeled A, B, and C on the diagram?
Warm, moist air that is less dense than the surrounding air
Which of the following ecosystem services are categorized as regulating?
pollination, decomposition, and water purification
