    • A. 

      Oxygen

    • B. 

      Carbon dioxide

    • C. 

      Nitrogen

    • D. 

      Ozone

  • 2. 
    The production of energy-rich ATP molecules is the direct result of
    • A. 

      Recycling light energy to be used in the process of photosynthesis

    • B. 

      Releasing the stored energy of organic compounds by the process of respiration

    • C. 

      Breaking down starch by the process of digestion

    • D. 

      Copying coded information during the process of protein synthesis

  • 3. 
    An experiment was set up to test the effect of light intensity on the rate of photosynthesis, as shown in the diagram below. Data were collected by counting gas bubbles released in a 5-minute period when the light source was placed at various distances from the experimental setup. The data are shown in the table below. The number of bubbles released when the light source is at a distance of 38 centimeters would most likely be closest to
    • A. 

      6

    • B. 

      10

    • C. 

      13

    • D. 

      22

  • 4.

    • A. 

      Respiration and replication

    • B. 

      Photosynthesis and excretion

    • C. 

      Digestion and recycling

    • D. 

      Circulation and coordination

  • 5. 
    Which process initially provides the link between an abiotic factor and the energy needs of an entire ecosystem?
    • A. 

      Respiration

    • B. 

      Photosynthesis

    • C. 

      Decomposition

    • D. 

      Predation

  • 6. 
    Much of the carbon dioxide produced by green plants is not excreted as a metabolic waste because it
    • A. 

      Can be used for photosynthesis

    • B. 

      Is too large to pass through cell membranes

    • C. 

      Is needed for cellular respiration

    • D. 

      Can be used for the synthesis of proteins

  • 7. 
    The diagram below represents events associated with a biochemical process that occurs in some organisms. Which statement concerning this process is correct?
    • A. 

      The process represented is respiration and the primary source of energy for the process is the Sun.

    • B. 

      The process represented is photosynthesis and the primary source of energy for the process is the Sun.

    • C. 

      This process converts energy inorganic compounds into solar energy which is released into the atmosphere.

    • D. 

      This process uses solar energy to convert oxygen into carbon dioxide.

    • A. 

      Chemical bonds between carbon atoms are formed during photosynthesis

    • B. 

      Energy stored in chemical bonds is released during cellular respiration

    • C. 

      Energy stored in nitrogen is released, forming amino acids

    • D. 

      Digestive enzymes break amino acids into smaller parts

  • 9. 
    In what way are photosynthesis and cellular respiration similar?
    • A. 

      They both occur in chloroplasts.

    • B. 

      They both require sunlight.

    • C. 

      They both involve organic and inorganic molecules.

    • D. 

      They both require oxygen and produce carbon dioxide.
