Photosynthesis and respiration are vital process for nearly earth’s entire biosphere. Which statement is false as it applies to photosynthesis and respiration concepts?

• Glucose and oxygen are produced by photosynthesis. Respiration produces carbon dioxide and water vapor. Both are part of how organisms obtain the energy they need to stay alive.

• Photosynthesis is used to make food molecules used by the plants.

  It means the oceans can store carbon dioxide dissolved in seawater.

• 
  

  It means that the oceans cannot absorb carbon dioxide.

• 
  

  It means that ocean plants give off carbon dioxide into the atmosphere.
