How can energy from the sun be transferred to animals?
The sun's energy is transformed into food by plants, animals eat plants as food so that they can transform that food into energy.
Plants produced energy through photosynthesis, animals that eat that energy can produce food.
Plants transformed energy of the sun into gases that animals can breath in to use as energy through respiration.
Animals are able to use energy from the sun by eating the plants that provides energy for the animals.
