    1. Multiple-choice 2 minutes Q.

    The diagram shows the amount of phosphorus measured in teragrams (1 teragram = 1×10^12) grams), in the various reservoirs of the phosphorus cycle. Which of the following is the best explanation for why there is such a small amount of phosphorus that moves into aquatic systems?

    answer choices

    Phosphorus is highly stable in the atmosphere and remains there for long periods of time.

    The amount of phosphorus in the cycle has been greatly reduced because of the use of catalytic converters in automobiles.

    There is not a gaseous phase of the phosphorus cycle, and therefore the movement of phosphorus into oceanic reservoirs is very slow.

    The phosphorus cycle occurs so rapidly that it does not exist in any one reservoir for a very long time.

    2. Multiple-choice 2 minutes Q.

    According to the diagram, the movement of phosphorus between biological organisms and soil is in a steady state in an undisturbed system. Which of the following best explains the reason for this steady movement?

    answer choices

    Phosphorus is taken up by plants during photosynthesis to create carbohydrates.

    A decrease in buffer zones prevents phosphorus runoff in waterways.

    There is a rapid influx of phosphorus from the weathering of rocks.

    Readily available organic phosphorus in the soil is assimilated by plants.

    3. Multiple-choice 2 minutes Q.

    Based on the diagram, which of the following reservoirs contains the most phosphorus?

    answer choices Plants Sediments Soil Oceans 4. Multiple-choice 2 minutes Q.

    The diagrams above show an area that was once a pasture that has since undergone changes to the vegetation over time. Which of the following changes in the hydrologic cycle is most likely to occur as a result of the change in vegetation in the area?

    answer choices

    Increased infiltration

    Increased runoff

    Decreased transpiration

    Decreased precipitation

    5. Multiple-choice 2 minutes Q.

    answer choices A B C D 6. Multiple-choice 2 minutes Q.

    Which letter correctly identifies a process of the hydrologic cycle in which the phase of water is changed from a liquid to a gas?

    answer choices A B C D 7. Multiple-choice 2 minutes Q.

    Which of the following best describes gross primary productivity in an ecosystem?

    answer choices

    Gross primary productivity is the total amount of energy captured by producers plus the energy used by consumers over time.

    Gross primary productivity is the total amount of energy captured by producers minus the energy that producers respire over time.

    Gross primary productivity is the total amount of energy lost as heat during energy transfer between trophic levels.

    Gross primary productivity is the total amount of solar energy captured by producers through photosynthesis over time.

    8. Multiple-choice 2 minutes Q.

    Which of the following best describes the net primary productivity of an ecosystem?

    answer choices

    Net primary productivity is the amount of energy captured by producers through photosynthesis over time.

    Net primary productivity is the amount of energy lost by producers through respiration over time.

    Net primary productivity is the amount of energy lost through respiration by producers subtracted from the gross primary productivity of an ecosystem.

    Net primary productivity is the amount of energy lost through respiration by producers added to the gross primary productivity of an ecosystem.

    9. Multiple-choice 2 minutes Q.

    Scientists calculated the net primary productivity at two different forest sites. Both forests have the same gross primary productivity. Forest A has a net primary productivity of 1,650kcal/m^2/year, and forest B has a net primary productivity of 1,110kcal/m^2/year. Which of the following statements is best supported by the data?

    answer choices

    Forest A has a higher rate of decomposition by bacteria than forest B.

    Forest A has more biodiversity than forest B.

    Forest A producers have lower rates of cellular respiration than forest B producers.

    Forest A producers have more biomass than forest B producers.

    10. Multiple-choice 2 minutes Q.

    Which of the following best describes the movement of energy in an ecosystem?

    answer choices

    Energy is constantly recycled by decomposers for use by producers.

    Energy is harnessed by producers, and available energy decreases with each trophic level transfer.

    Energy is absorbed by plants through water and soil and then moves up the food chain through consumers.

    Energy is magnified as it moves up the trophic levels, and tertiary consumers store the most energy in a food web.

    11. Multiple-choice 2 minutes Q.

    The table above shows the balanced chemical equations that represent three processes that are part of the nitrogen cycle. Which of the following is exemplified by the equations above?

    Resource partitioning of the seeds reduces competition, and the five different species can live in the same tree.

    Five different species of warblers, seed-eating birds, live in the same species of conifer trees. All of the birds migrate to coniferous forests during the summer, and different species reside in different areas in the same tree. They feed on the seeds of the conifer trees, but the different species do not mate with each other.

    Which of the following best explains why the different warbler species can all have habitats in the same conifer trees?

    Niche overlap occurs between the five different species, and living in the same tree increases competition for seeds.

    Not all the warblers are residents in the forest at the same time of the year because of different migration patterns.

    Physiological differences in beak structure allow the warblers to consume different species of seeds through symbiotic relationships.

    Resource partitioning of the seeds reduces competition, and the five different species can live in the same tree.

    The chance of survival decreases when there is intraspecific competition for resources among surviving yearlings.

    In a fish species, the number of eggs that hatch and survive for one year varies depending on the number of eggs that were produced. As the number of eggs produced increases past a threshold number, the survival rate of the offspring decreases.
