radiant energy for nuclear energy radiant energy for thermal energy thermal energy for nuclear energy nuclear energy for chemical energy
I gave my students this multiple choice question: A greenhouse is an example of a closed system. Which two types of energy are exchanged in this system?

Only one answer is correct among these 4 choices:
- radiant energy for nuclear energy
- radiant energy for thermal energy
- thermal energy for nuclear energy
- nuclear energy for chemical energy

Could you tell me which one is correct?
