How can energy from the sun be transferred to animals?
The sun's energy is transformed into food by plants, and animals eat plants so that they can transform that food into energy.
Plants produce energy using the sun's energy, and animals then eat that energy.
Plans transform the sun's energy into gases that animals can breath in to use as energy.
Animals produce their own food using energy from the sun. They don't need plants.
