How does the Sun provide us with energy we need to run our bodies?

The sun radiates a lot of things we need like vitamin D and heat. It also is the energy source of organisms that survive off of photosynthesis, like plants, which we or other consumers eat.

It's like this:

Sun--->Producers (Plants and Protists) - - - > Consumers (animals and humans) - - - > Decomposers (mostly bugs, bacteria, and fungi)

The sun provides vitamin D and it also feeds the plants which feeds the animals which we eat and we eat for energy
