The digestive system not only processes the foods we eat but it is also the site of some nutrient production. which two nutrients are produced by bacteria that live in the large intestine?

Answer :

Commensal bacteria are friendly bacteria in the large intestine. These bacteria produce Vitamin K and Biotin (a B Vitamin). The bacteria may be a source of these vitamins, but if a person depends solely on the bacteria for these vitamins, the person may become vitamin-deficient especially if they are treated with antibiotics that can kill commensal bacteria.
