3 (solar to chemical, chemical to kinetic, kinetic to thermal)
Explanation:
Michael ate a salad. The salad which he consumes becomes chemical energy, but the tomato he put in his salad has used solar energy, which is simply energy from the sun. The kinetic energy is when he runs 2 miles as kinetic energy is the energy gained from movement. When he stops running, he sweats, which means he is losing heat from his body, therefore the kinetic energy store transfers to the thermal (internal) energy store.
I hope this helps!! ^-^
