Which gas do you need for combustion/respiration?
carbon dioxide
oxygen
nitrogen
What is the fuel during this combustion?
The flame

You see in this image a walking leaf in the attack position. It is in the light. It eats leaves. Suppose there is no food for it, could it keep itself alive with its own body?
Yes, it can do photosynthesis itself
No, it can only do respiration
Yes, because it can do both photosynthesis and respiration
