Horse Digestion microorganisms live in the caceum produces cellulases feces are fibrous --> evolved but not perfect due to improper location Rabbit Digestion change in behaviour NOT anatomy Eat grass, produce feces at night Eat feces in the AM cellulase goes through digestive tract second time very efficient Ruminant Digestion both change in anatomy and behaviour no fibrous material in feces = all hydrolyzed chamber contain mutualistic microorganisms that digest cellulose
