chemical energy kinetic energy light energy heat energy
I gave my students this multiple choice question: When plants undergo photosynthesis, a reaction produces sugar, oxygen, and water. During respiration, stored energy from the products of photosynthesis is converted to usable energy. In what form is the energy stored prior to use in respiration?

Only one answer is correct among these 4 choices:
- chemical energy
- kinetic energy
- light energy
- heat energy

Could you tell me which one is correct?

chemical energy
