Answer 1

~~You’re~~ Your food.

One of the ways your body gains energy is to get the carbon atoms in your food and combine them with oxygen.

When done in the particular way your body is able to do it, this releases chemical energy such that the biological machinery in your cells can harness it.

This produces cardon dioxide too, and we breathe out those molecules to get that waste out of our system.
