Quiz Preview

  • 2. 

    The term "cycle" is used in nutrient cycles because.

    • They have two parts like the two wheels of a "bicycle".

    • Their steps always form a long ring, like a snake biting its tail.

    • The nutrients always get cycled and recycled through the many paths of the system.

    Correct Answer
    A. The nutrients always get cycled and recycled through the many paths of the system.
  • 3. 

    Which problem is caused by an unbalanced Carbon Cycle?

    • Global Warming

    • Eutrophication

    • Flooding

    Correct Answer
    A. Global Warming
  • 4. 

    The Greenhouse Effect is a problem that occurs when.

    • A water body is destroyed by excess nutrients like nitrogen.

    • Excess CO2 causes too much heat to be trapped in the earth's atmosphere.

    • A greenhouse plant receives too much fertilizer.

    Correct Answer
    A. Excess CO2 causes too much heat to be trapped in the earth's atmosphere.
  • 5. 

    What is nitrogen used for?

    • To make rain, sleet, and snow

    • To make proteins

    • To make living thing

    Correct Answer
    A. To make proteins
  • 6. 

    Which TWO cycles use bacteria and fungi, which are decomposers, that help the cycle?

    • Water Cycle

    • Carbon Cycle

    • Nitrogen Cycle

    Correct Answer(s)
    A. Carbon Cycle
    A. Nitrogen Cycle
    Explanation
    Bacteria break down dead organisms to return carbon back into the system. Bacteria break down animal waste to give usable nitrogen back to the system.

    Which process makes clouds?

    • Condensation

    • Precipitation

    • Evaporation

    • Runoff

    Correct Answer
    A. Condensation
  • 8. 

    Select TWO (2) activities that are part of the NITROGEN CYCLE.

    • A. Photosynthesis turns CO2 into sugar

    • B. Respiration turns sugar into CO2

    • C. Animal waste can be converted by bacteria to form nitrates (NO3).

    • D. Nitrogen-fixing bacteria  change nitrogen in the air (N2) to nitrates (NO3) for use.

    Correct Answer(s)
    A. C. Animal waste can be converted by bacteria to form nitrates (NO3).
    A. D. Nitrogen-fixing bacteria  change nitrogen in the air (N2) to nitrates (NO3) for use.
  • 9. 

    Select TWO (2) events that are part of the CARBON CYCLE.

    • Nitrogen fixing bacteria change atmospheric nitrogen gas to nitrates.

    • Respiration turns sugar (C6H12O6) into CO2.

    • Eutrophication results from excess fertilizer.

    • Photosynthesis turns CO2 into sugar (C6H12O6).

    Correct Answer(s)
    A. Respiration turns sugar (C6H12O6) into CO2.
    A. Photosynthesis turns CO2 into sugar (C6H12O6).
  • 10. 

    What two things help to change nitrogen in the air to the correct form of usable nitrogen (nitrate)?

    • Burning

    • Bacteria

    • Lightning

    • Heterotrophs

    Correct Answer(s)
    A. Bacteria
    A. Lightning
  • 11. 

    Eutrophication is the situation where....

    • The atmospheres receives too much carbon and it traps more heat.

    • A water body is damaged by excess nutrients like nitrogen.

    • A piece of land is over fertilized.

    Correct Answer
    A. A water body is damaged by excess nutrients like nitrogen.
