The bacteria in our large intestine break down food that we consider waste. During this process, vitamins are released that we absorb into our bloodstream. This is an example of which symbiotic relationship?

This is a mutual symbiotic relationship were both the partners benefit from the process. In this case, the bacteria break down the food that is considered waste with facilitates its survival and on the other hand the human body obtains vitamins that are released in the bloodstream for absorption.

I believe the correct answer is commensalism.
