Introduction to Photosynthesis and Energy Flow in Organisms

If a person could not digest food anymore, what would probably happen to that person? Why?

• The person would gain weight because the undigested food would sit in the person's body.

• The person would not lose or gain weight, but it would take longer for the body to use the food that was eaten.

• The person would lose weight because most of the molecules from food could not be used for building materials.

• Nothing would change because digestion does not affect the way food is used by the body.

Which organisms store some of the molecules from food in their bodies to use later as a source of chemical energy and building materials?

• Both animals and plants

• Animals but not plants

• Plants but not animals

• Neither animals nor plants
