Original Project
Matter and Energy in Living Systems
All organisms need food as a source of molecules that provide chemical energy and building materials.
Item BF003005: If a person could not digest food anymore, the person would lose weight because most of the molecules from food could not be used for building materials.
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.
