Questions and Answers
  • 1. 
    In some parts of the world, rain forests are being cut down to make land available for new homes. How does the loss of these trees impact the carbon cycle? 
    • A. 

      The trees will no longer be able to undergo photosynthesis which will decrease the amount of oxygen within the atmosphere.

    • B. 

      The trees will no longer be able to undergo photosynthesis which will decrease the amount of carbon removed from the atmosphere.

    • C. 

      The trees will no longer be able to undergo respiration which will cause the amount of carbon within the atmosphere to be removed.

    • D. 

      The trees will no longer be able to undergo respiration which will decrease the amount of fossil fuels produced.

  • 2. 
    Evaluate the following statements and decide which of the following best describes the role of bacteria in the nitrogen cycle.
    • A. 

      Bacteria turn oxygen into nitrogen for plants to use.

    • B. 

      Bacteria turns nitrogen into a usable form called ammonia for plant use.

    • C. 

      Bacteria turns carbon dioxide into oxygen during the process of photosynthesis.

    • D. 

      Bacteria turn nitrogen into a usable form in a process called transpiration.

  • 10. 
    Analyze the following statement.  Which response best describe how matter and energy are cycled through the ecosystem? 
    • A. 

      Energy is recycled in an ecosystem, but matter is not recycled.

    • B. 

      Energy is gained in the next tropic level, and matter is lost in an ecosystem.
