The energy that a piece of food has is transformed when a person's digestive system processes the food. That chemical energy from the food is transformed into many other types of energy. How does the amount of chemical energy of a piece of food compare to the amount mechanical and kinetic energy the person receives once the chemical energy is
transformed?

1. The amount of chemical energy is equal to the amount of mechanical and kinetic energy.

2. The amount of chemical energy is less than the amount of mechanical and kinetic energy

3. The amount of chemical energy is more than the amount of mechanical and kinetic energy

Answer :

Answer:

3. The amount of chemical energy is more than the amount of mechanical and kinetic energy

Explanation:

1) Digestion is not 100% efficient so some of the chemical energy is expelled as waste.

2) A lot of energy is converted to heat to keep the body warm even without motion or potential energy changes.
