Part I: Bozeman Video Review on AP Biology Practices A practice is a way to coordinate knowledge and skills in order to accomplish a goal or task. The AP Biology science practices enable you to establish lines of evidence and use them to develop and refine testable explanations and predictions of natural phenomena. Because content, inquiry, and reasoning are equally important in AP Biology, each learning objective combines content with inquiry and reasoning skills described in the science practices. The science practices capture important aspects of the work that scientists engage in, at the level of competence expected of you, an AP Biology student. To review the AP Biology science practices, log onto http://www.bozemanscience.com/ap-biology/. Scroll down to AP Biology Practices.

Here are some EXAMPLE test essay questions. Students who have completed the summer assignment completely, thoroughly, and correctly should be able to answer each question below. YOU ARE NOT REQUIRED TO ANSWER THESE AS PART OF YOUR SUMMER ASSIGNMENT, BUT YOUR TEACHER HIGHLY RECOMMENDS THAT YOU PRACTICE THEM BEFORE YOUR EXAM! Rubrics for these questions are available by emailing Mrs. Carnes or Mrs. Yamin. Practice Essay Question #1 A biologist measured dissolved oxygen in the top 30 centimeters of a moderately eutrophic (mesotrophic) lake in a temperate zone. The day was bright and sunny, and the wind was calm. The results of the observations are presented below: a) Plot the results that were obtained. Then, using the same set of axes, draw and label an additional line/curve representing the results that you would predict had the day been heavily overcast. b) Explain the biological processes that are operating in the lake to produce the observed data. Explain also how these processes would account for your prediction of results for a heavily overcast day. c) In most aquatic environments, primary production is affected by light available to the community of organisms. Using measurements of dissolved oxygen concentration to determine primary productivity, design a controlled experiment to test the hypothesis that primary productivity is affected by intensity of light. In your answer, be sure to include the following. A statement of the specific hypothesis that you are testing; A description of your experimental design (be sure to include a description of what data you would collect and how you would present and analyze the data using a graph); A description of results that would support your hypothesis. Practice Essay Question #2 Consumers in aquatic ecosystems depend on producers for nutrition. a. Explain the difference between gross and primary productivity. b. Describe a method to determine net and gross primary productivity in a freshwater pond over a 24-hour period. In an experiment, net primary productivity was measured, in the early spring, for water samples taken from different depths of a freshwater pond in a temperate deciduous forest. c. Explain the data presented by the graph, including a description of the relative rates of metabolic processes occurring at different depths of the pond. d. Describe how the relationship between net primary productivity and depth would be expected to differ if new data were collected in midsummer from the same pond. Explain your prediction. Practice Essay Question #3 The element carbon is contained in all organic compounds. (a) Discuss the role of photosynthesis and cellular respiration in carbon cycling in the biosphere. (b) For THREE of the following, predict and explain the effect on the carbon cycle if: Decomposers were absent Deforestation occurred Volcanic dust accumulated in the atmosphere The average ocean temperature increased (c) Explain how increased CO 2 in the atmosphere results in greater acidification of oceans and describe the effect on marine organisms. Include in your discussion TWO examples of how human activity can increase atmospheric CO 2.
Practice Essay Question #4 On a trip to a dense forest, a biologist noticed that millipedes (small invertebrates) were plentiful under logs but were rarely seen in any other location. (a) Propose THREE environmental variables (two abiotic and one biotic) that could explain why millipedes were plentiful under logs but were rarely seen in any other location. (b) For ONE of the abiotic environmental variables you chose above, design a controlled experiment to test a hypothesis that this factor affects the distribution of milliedes on the forest floor. Describe data that would support your hypothesis. (c) Suppose you were examining the distribution of a plant, instead of millipede. Describe modification in the experiment that you designed in (b) that would be required to determine whether the abiotic factor you chose affects the distribution of the plant. Practice Essay Question #5 Ecological succession describes the pattern of changes in communities over time. The graph below shows changes in lant diversity following the abandonment of an agricultural field in a temperate biome. (a) Discuss the differences in plant diveristy shown in the graph and explain how the changes affect the animal species composition between years 0 and 120. (b) Identify TWO biotic and TWO abiotic factors and discuss how each could influence the pattern of ecological succession. (c) Design a controlled experiment to determine how the diversity of plant species in a newly abandoned field would be affected by large herbivores. Practice Essay Question #6 The energy flow in ecosystems is based on the primary productivity of autotrophs. (a) Discuss the energy flow through an ecosystem and the relative efficiency with which it occurs. (b) Discuss the impact of the following on energy flow on a global scale: Deforestation Global Climate Change (c) There are vast stores of organic matter in the soils of northern coniferous forests and tundra around the world. Based on your understanding of decomposition rates and nutrient cycling, suggest an explanation for why scientists who study global warming are closely monitoring these stores.
Practice Essay Question #7 In many ways, all organisms in a food web can be said to be solar-powered. The producer level of the food web is responsible for the transformation of the solar energy into a form that can be used by other living organisms. (a) Discuss the role of green plants in transforming the Sun s energy into a form that can ultimately be used by heterotrophs. (b) Discuss the flow of energy from producers through top carnivores in a food web in terms of the laws of thermodynamics. Practice Essay Question #8 Interdependence in nature is illustrated by the transfer of energy through trophic levels. The diagram below depicts the transfer of energy in a food web of an Arctic lake located in Alaska 1. Choosing organisms from FOUR different trophic levels of this food web as examples, explain how energy is obtained at each trophic level. 2. Describe the efficiency of energy transfer between trophic levels and discuss how the amount of energy available at each trophic level affects the structure of the ecosystem. 3. If the cells in the dead terrestrial plant material that washed into the lake contained a commercially produced toxin, what would be the likely effects of this toxin on this food web? Explain. Practice Essay Question #9 Invasive species, such as red fire ants, introduced into an ecosystem often threaten native plants and animals. (a) Describe THREE different factors that contribute to the success of invasive species in an ecosystem. (b) Discuss THREE ways that an invasive species can affect its new ecosystem. (c) The map below indicates the spread of the red fire ant after its initial entrance into the United States at the port of Mobile, Alabama, in the 1930s. Discuss TWO environmental factors that might have determined the pattern of fire ant invasion. (d) Discuss TWO possible methods of eradicating or slowing the spread of these ants, including the environmental consequences of each method.
