Ap envirionmental science unit 2 final
Which statement is best supported by the data in the graph?
Finches with larger beaks were more likely to survive in 1980 because they were able to feed primarily on seeds and nuts during the drought.
Based on the graph above, which of the following years postdisturbance had the greatest species richness?
250
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 service that would provide protection from a hurricane storm surge?
An intact coastal wetland
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
Which of the following best identifies the author's claim?
Anthropogenic disruptions to Earth's resources can have sudden and severe negative consequences to the health of native species, specifically those whose populations are already threatened.
The image shows two different islands and the relative distance to the nearest mainland. Based on the theory of island biogeography, which of the following best predicts the effect of the introduction of an invasive species on Easter Island compared to Madagascar?
The native species on Madagascar are more likely to survive because the island is larger and provides a greater diversity of habitats and resources.
Based on the data in the graph, 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 the population and the percentage of light-colored moths decreased in the population.
Which of the following best identifies the author's claim?
Acidic water affects the salmon's ability to sense danger from attacking predators by their sense of smell.
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's 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 CO2CO2 concentration and Antarctic temperature are directly correlated over the past 800,000800,000 years.
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.
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 of the following best describes Ecosystem C?
Its low habitat diversity indicates that Ecosystem C most likely has a low number of specialist species and few species that utilize large territories.
Which of the following best identifies the author's claim?
Observed adjustments in the ecological tolerance of a species of reef fish is a result of epigenetic changes.
Which of the following ecosystem services is 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?
The collapse of local fisheries, because of the damage to coral reefs from ocean acidification
Which of the following best describes the pattern in the atmospheric CO2 concentration data over the past 200,000 years?
The concentration of CO2CO2 fluctuated between 150ppm150ppm and 250ppm250ppm until recently, when the concentration rose exponentially.
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 12°C12°C and then decreases by about 12°C12°C.
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 graphs best demonstrates the change in the frequencies of light-colored moths and dark-colored moths in the population from 1950 to 2000?
where the dark line and the dashed line are intertwining
