In a way you're correct OP, our energy does come from the sun, but not exactly as you imagine it. We don't absorb it as radiation, but we do take in
its energy through food.
The food is broken down in our bodies, until all the protein, fats and sugars are ultimately converted to energy inside our cells, the mitochondria to
be exact. Mitochondria is also known as the Cell's Powerhouse, and it converts the food molecules into our main energy carrier, ATP or adenosine tri
phosphate. ATP's chemical bonds carry very high energy.
So it all begins with photosynthesis in plants, and they convert sunlight into food for their mitochondria. Animals, us, then eat the plants and other
things for that stored energy. Any animal could stand out in the sun for days and it wouldn't absorb any radiation from the sun and would die, but
give it food and it makes its own energy.
