Which of the following best identifies the author's claim? A Acidic water affects the salmon's ability to sense danger from attacking predators by their sense of smell. B Salmon can only tolerate certain water temperatures before all of their senses are severely damaged. C Acidic water prevents salmon from maturing and therefore from being able to reproduce and replenish declining salmon populations. D Acidic water is causing a rise in the population of predators as a result of the salmon's increased ability to smell predators.

Which of the following best identifies the author's claim? A Observed adjustments in the ecological tolerance of a species of reef fish is a result of epigenetic changes. B Climate change is damaging coral reefs as a result of warming ocean waters, which affect reef fish survival. C Transferring specific gene sequences of the spiny chromis damselfish to other fish species will help populations acclimate to warming ocean temperatures. D Continued acclimation of fish populations through epigenetics to warmer oceans will eventually replace the process of natural selection.

Which of the following economic consequences to a provisioning ecosystem service will most likely result from increased global warming? A The collapse of local fisheries, because of the damage to coral reefs from ocean acidification B Loss of revenue from the oil industry, because of increased oil spills from offshore oil wells C Widespread crop failure, because of increased acid precipitation in agricultural areas D Increased cost for water filtration, because of loss of coastal wetlands

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? A The percentage of dark colored moths increased in the population and the percentage of light-colored moths decreased in the population. B The percentage of dark-colored moths decreased in the population and the percentage of light-colored moths increased in the population. C The percentage of dark colored moths decreased in the population after 1850 and the percentage light-colored moths remained constant throughout the time period. D The percentage of both the dark-colored moths and the light-colored moths remained constant throughout the time period.

(using graph on ap classroom) Which statement is best supported by the data in the graph? A Finches were better able to find mates, and the population size increased in 1977 because of the abundance of grasses. B 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 The average beak size in 1981 increased to 9.8mm because finches had access to unlimited resources. D The finch population declined from 1983 to 1984 due to a decrease in habitat.

b

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? A As predation increases, the population size of the invasive generalist species will decrease. B As competition for resources increases, the population size of the island's specialist species will decrease. C As resources are partitioned, the population sizes of both the generalist species and the specialist species will increase. D As niches overlap, the invasive generalist species will be outcompeted by the island's specialist species.

b

Based on the graph above, which of the following years post-disturbance had the greatest species richness? A 25 B 100 C 175 D

b

Based on the theory of island biogeography, which of the following islands would most likely have the highest number of species living on it? A An island 30 hectares in size that is 30 kilometers off the coast of the mainland B An island 30 hectares in size that is 10 kilometers off the coast of the mainland C An island 10 hectares in size that is 30 kilometers off the coast of the mainland D An island 10 hectares in size that is 10 kilometers off the coast of the mainland

b

Which of the following best describes the pattern in the atmospheric CO2 concentration data over the past 200,000 years? A The concentration of CO2 fluctuated between 150ppm and 250ppm. B The concentration of CO2 fluctuated between 150ppm and 250ppm until recently, when the concentration rose exponentially. C The concentration of CO2 remained constant at first from 200,000 years ago until 50,000 years ago, and then began a steady decline. D The concentration of CO2 rose exponentially to 400ppm and leveled off at carrying capacity.

b

Which of the following ecosystem services are categorized as regulating? A Wood fuel, medicine, and potable water B Pollination, decomposition, and water purification C Recreation, education, and aesthetics D Photosynthesis, nutrient cycling, and creation of soils

b

Which of the following is an example of an ecosystem that provides ecosystem services including protection from hurricane storm surges? A A lock and dam system B An intact coastal wetland C An energy-producing tidal barrage system D An offshore, deep-water fish farm

b

(using article on ap classroom) Which of the following best identifies the author's claim? A The 2008 die-off of the gharials was caused by extensive overfishing of the Chambal River, leaving little food for the reptiles. B The gharials have a wide ecological tolerance range, so it is unlikely that changes to the water chemistry of the Chambal River would have caused the 2008 die-off. C 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. D In light of the 2008 die-off of the gharials, Indian government officials need to enact stricter laws to prevent the illegal dumping of drugs and other pollutants into the Chambal River.

A The temperature increases by about 10°⁢C. B The temperature decreases by about 8°⁢C. C The temperature increases by about 12°C and then decreases by about 12°⁢C. D The temperature decreases by about 10°⁢C and then increases by about 12°⁢C.

(using image on ap classroom) 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? A The native species on Easter Island are more likely to survive because the island is further from the mainland. B The native species on Easter Island are more likely to survive because the island is so small that there will be limited space for an invasive species to colonize. C The native species on Madagascar are more likely to survive because the island is larger and provides a greater diversity of habitats and resources. D The native species on Madagascar are more likely to survive because the temperature in the Indian Ocean is warmer than that of the Pacific Ocean.

Based on the information above, which of the following best describes Ecosystem C? A Its low species diversity indicates that Ecosystem C most likely has species with very low population sizes. B Its high genetic diversity indicates that Ecosystem C most likely has species that evolve quickly. C Its high genetic diversity indicates that Ecosystem C is most likely the result of the founder effect and a subpopulation originating from Ecosystem A. D Its low habitat diversity indicates that Ecosystem C most likely has a low number of specialist species and few species that utilize large territories.

d Its low habitat diversity indicates that Ecosystem C most likely has a low number of specialist species and few species that utilize large territories.

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
