How is the sun a good source of vitamin d if all you are receiving is photons?

In: Biology

Answer 1

The sun sends little pieces of energy at us all the time. That’s what light is. These little pieces of energy are very helpful at turning useless things into good things. Plants are experts at using this to create food, but that’s just one example. One of the things that the sun’s energy changes pretty quickly is stored in our body, and this energy hits it and the energy turns it into something else, in this case, a vitamin that we need.
