Let's look at photosynthesis so you've gotta plants leaf and when sunlight hits the plant's leaf. They will absorb the photons of energy. Sounds like star trek but it absorbs photons and then the plant will convert that into food through photosynthesis so that's one simple way that living organisms can use light in humans when sunlight hits us.
