The law of conservation of energy states that energy cannot be created or destroyed but can be converted or transferred. So when you're eating a burger which has chemical energy, it is transferred to mechanical energy if you go out and ride a bicycle. Another example is when the Sun which is thermal energy shines on the apple tree, it is converted to chemical energy because the apple has chemical energy. Transferred is pretty similar.
