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

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

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)
