Describe energy transfer starting with the sun and ending with a human and a hand crank generator. Make sure to include some chickens too.
Energy is provided by the sun, which transfers energy to plants, which provides energy to chickens, which provide energy to humans, who use kinetic energy when turning the hand crank.
