Dr Keshav Singh Associate Professor Department of Zoology DDU Gorakhpur University Gorakhpur Digestion The digestive system of the human body comprises a group of organs working together to convert food into energy for the body . WHY USE SIMULATION?. Anaerobic digestion is a highly complex process containing numerous biological and chemical reactions taking place simultaneously. The stability of an anaerobic digestion system depends on the composition of the substrates and how microorganisms themselves convert the given substrates. . Presented by: Milagro Chavez.

Besides water, the diet must provide metabolic fuels (mainly carbohydrates and lipids), protein (for growth and turnover of tissue proteins), fiber (for roughage), minerals (elements with specific metabolic functions), and vitamins and essential fatty acids (organic compounds needed in small amounts for essential metabolic and physiologic functions). . 267 The digested end products are absorbed into the body through the epithelial liningof the intestinal villi.
