- Q1Surtsey is an island located south of Iceland. The island was formed by a volcanic eruption and first appeared in 1963. The table below contains descriptions of changes in the population and diversity of species on Surtsey. Which of these lists the descriptions in the correct order of ecological succession on Surtsey?II, IV, I, IIII, II, IV, IIIIV, III, I, IIIII, I, II, IV60sBIOL.11b
- Q2The overgrowth of algae poses a major problem for coral reefs. Intensive fishing is one factor that contributes to algae overgrowth because it does which of the following?Reduces the number of organisms that feed on algaeInhibits the spread of pathogens in algae coloniesIncreases the competition between different algae speciesAllows more sunlight to be available to algae60sBIOL.12e
- Q3Which of the following are missing from the food web shown above?OmnivoresPredatorsDecomposersProducers60sBIOL.12c
- Q4The acacia ant (Pseudomyrmex ferruginea) lives in the bullshorn acacia plant, as shown below. The acacia ant nests and feeds in the plant's hollow thorns. The ant helps protect the bullshorn acacia by attacking insects and grazing animals that come near the plant. The relationship between the acacia ant and the bullshorn acacia is an example of which of the following?CommensalismMutualismParasitismNeutralism60sBIOL.12a
- Q5The carbon cycle includes processes that release carbon into the atmosphere and places that act as carbon reservoirs. The diagram below shows both major processes that release carbon and major carbon reservoirs. Which of these disruptions would cause an excess output in the carbon cycle?Increases in marine biotaA thickening of ocean sedimentsA reduction in the use of fossil fuelsThe destruction of terrestrial biota60sBIOL.12d
- Q6The Nile River flows into the Mediterranean Sea. The Aswan High Dam contains the flow of water from the river and reduces the annual fall flooding. The floodwater is trapped behind the huge dam, allowing irrigation for agriculture. Sediments that would be washed away by the annual floods are also trapped behind the dam. The graph shows the water flow from the Nile that enters the Mediterranean Sea. How has this dam most likely affected the Mediterranean Sea ecosystem?Reduced nutrients from the land support fewer producers in the seaThe flooding in August through November causes marine life to be destroyedThe water temperature of the sea has increasedWater trapped behind the dam causes the marine ecosystem to move inland60sBIOL.12e
- Q7The Texas blind salamander (Eurycea rathbuni) lives in the Edwards Aquifer region around San Marcos. Along with other species the salamander lives in total darkness in the underground crevices and caves of the aquifer region. The table lists some of the organisms that live in this environment and their food sources. In an energy pyramid for these aquifer cave dwellers, which of the following would be placed at the bottom?ProtozoaBlind shrimpSnailsTexas blind salamanders60sBIOL.12c
- Q8A student sets up a compost bin outdoors. Inside the bin microorganisms convert the student's vegetable and paper scraps into rich fertilizer. Which of the following best describes the role that these microorganisms play in natural habitats?The microorganisms function as autotrophsThe microorganisms help balance the numbers of producers and consumersThe microorganisms turn solar energy into sugarsThe microorganisms help keep nutrients cycling through the ecosystem60sBIOL.11a
- Q9The graph shows the basic changes in a forest community after a disturbance occurred. The information shown in the graph suggests that the changes in the forest community were caused by -succession after a firerepeated habitat destructiondecreased species diversitytree-leaf replacement after a storm60sBIOL.11b
- Q10The iris controls the size and shape of the pupil. Which eye most likely belongs to an animal that is active most of the day on white desert sand?60sBIOL.12b
- Q11A native species and a non-native species are competing for resources within the same ecosystem. The non-native species is more likely to survive than the native species in which of the following situations?The native species is immune to certain pathogens in the ecosystemThe non-native species has no natural enemies in the ecosystemPredators prey on both native and non-native speciesBoth the native species and the non-native species thrive on the same food source60sBIOL.12a
- Q12The table below provides some information about the feeding methods of the five rhinoceros species. Which rhinoceros species is best adapted for feeding in the large open grasslands of Africa's Serengeti ecosystem?Javan rhinocerosBlack rhinocerosWhite rhinocerosSumatran rhinoceros60sBIOL.12b
- Q13Dead zones are low-oxygen areas that develop on the seafloor. Scientists hypothesize that phytoplankton blooms cause these dead zones. Phytoplankton blooms occur when excess nutrients are introduced by pollution from fertilizers, sewage plants, and the burning of fossil fuels. Which of the following would most likely cause an increase in these contributors to dead zones?Rainfall patterns that increase freshwater runoff from terrestrial ecosystemsConstructing efficient water-recovery and treatment plantsReplacing coal-fired power plants with windmillsFarming practices that reduce nitrate and phosphate applications60sBIOL.12e
- Q14Some fungi secrete substances that are toxic to bacteria that compete with them for food. Scientists have used their knowledge of this ability of fungi in order to produce which of the following substances?PlasticYogurtAntibioticsFertilizers60sBIOL.11a
- Q15A marine ecosystem is represented below. What is lost to the environment at each of the trophic levels of this ecosystem?Food sourcesHeatLiving space for the organismsNutrients from the soil60sBIOL.12c
