Which of the following ecosystem services is categorized as regulating?

Pollination, decomposition, and water purification

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 post disturbance had the greatest species richness?

100

Based on the graph above, which of the following years post disturbance did sweetgum experience the greatest biomass?

50

Which of the following best identifies the authors claim? (Q12)

Acidic water affects the Salmons ability to sense danger from attacking predators by their sense of smell

Which of the following is an example of an ecosystem service that would provide protection from a hurricane storm surge?

And 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?

And island 30 hectares in size that is 10 kilometers off the coast of the mainland

Which of the following best identifies the authors claim? (Q10)

Anthropogenic disruptions to earths resources can have sudden and severe negative consequences to the health of native species, specifically those whose populations are already threatened.

An island off the coast of Africa contains a larger percentage of specialist species then 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 islands specialist species will decrease

Which of the following best describes the trend in atmospheric CO2 concentration and antarctic temperature over the past 800,000 years?

Atmospheric CO2 concentration and antarctic temperature directly correlated over the past 800,000 years

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

Ecosystem b Genetic diversity: medium species diversity: high habitat diversity: medium

In the 1970s, the amount of industrial pollution decreased in the trees began to return to their preindustrial appearances. 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? The dark-colored moths are represented with a solid line in the light-colored moths are represented with a dashed line

Choice C (dashed line slightly wiggles at the bottom than exponentially increases and solid line wiggles at the top than exponentially decreases)

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

Ecosystem a, because it's low genetic diversity could've resulted from an event that reduced the variation in the gene pool

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

It's 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 authors claim? (Q11)

Observed adjustments in the ecological tolerance of a species of reef fish is a result of epigenetic changes

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 reef's 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 CO2 fluctuated between 150 ppm and 250 ppm until recently, when the concentration rose exponentially

The image shows two different islands in 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 invasive species on Easter island compared to Madagascar?

The native species of 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 describes the change in Antarctic temperature from about 440,000 years ago to about 340,000 years ago?

The temperature increases by about 12°C and then decreases by about 12°C

Based on the graph above, which of the following tree species would be the pre-dominant species found during the intermediate stage of succession?

Tulip poplar
