  • Q:

    Rabbits digest most of their food in their hindgut - their large intestine and cecum. Part of the digested material is passed as feces while part is passed as a nutritious cecotrope which is then consumed once more. Assuming the rabbit digestive system is otherwise like a human digestive system, which of the following is most likely the reason for the consumption of the cecotrope?



    rabbits have poor vision and are unable to distinguish food from the cecotrope


    the digested contents of the cecotrope must be mixed with food to aid digestion in the stomach


    the cecotrope needs a second pass through the digestive system for the nutrients to be properly absorbed in the hindgut


    most nutrient absorption happens in the small intestine so the digested cecotrope must be re-ingested so it will pass through the small intestine for nutrient absorption
