  • Q1
    Which of the following best explains why terrestrial trophic pyramids usually do not have levels higher than tertiary consumers?
    Tertiary consumers are often indicator species and are the first to be affected by environmental disturbances.
    A large proportion of energy is lost as heat as it is transferred up the pyramid, so there is not enough energy available to support another level.
    Tertiary consumers are the largest organisms in an ecosystem and require the most space to survive.
    Plants can only perform photosynthesis during the day, so tertiary consumers cannot get enough energy from consuming plants.

  • Q4
    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?
    Question Image
    Approximately 10% of energy is transferred from one trophic level to the next.
    The major reserve for nitrogen is in the atmosphere.
    Each biogeochemical cycle demonstrates the conservation of matter.
    In a food web, energy flows and matter is cycled.

  • Q6
    Which of the following best describes the movement of energy in an ecosystem?
    Energy is magnified as it moves up the trophic levels, and tertiary consumers store the most energy in a food web.
    Energy is absorbed by plants through water and soil and then moves up the food chain through consumers.
    Energy is harnessed by producers, and available energy decreases with each trophic level transfer.
    Energy is constantly recycled by decomposers for use by producers.

  • Q7
    In a given ecosystem, producers convert solar energy into 15,000 kcal of chemical energy stored in organic compounds. Which of the following is the most likely amount of energy available to secondary consumers?
    1,500 kcal
    1.5 kcal
    13,500 kcal
    150 kcal

  • Q8
    Which of the following best describes gross primary productivity in an ecosystem?
    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 energy captured by producers plus the energy used by consumers over time.
    Gross primary productivity is the total amount of solar energy captured by producers through photosynthesis over time.

  • Q9
    Which of the following best describes the net primary productivity of an ecosystem?
    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 added to the gross primary productivity of an ecosystem.
    Net primary productivity is the amount of energy lost through respiration by producers subtracted from the gross primary productivity of an ecosystem.
