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?

native species on Madagascar are more likely to survive because the island is larger and provides a greater diversity of habitats and resources.

Which of the following best describes the change in Antarctic temperature from about 440,000years ago to about 340,000 years ago?

temperature increases by about 12°C then decreases by about 12°⁢C.

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

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

50

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.

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

Ecosystem C most likely has a low number of specialist species and few species that utilize large territories.

Researchers in the Galápagos Islands measured the average beak size in a population of finches from 1976 to 1984, as shown in the graph below.

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. 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 best describes the pattern in the atmospheric CO2 concentration data over the past 200,000years?

fluctuated between 150ppm and 250ppm until recently, when the concentration rose exponentially.

Which of the following is an example of an ecosystem that provides ecosystem services including protection from hurricane storm surges?

An intact coastal wetland
