folio-, foli-, folii-
(Latin: leaf, leaves; a plant's device for intercepting light, obtaining and storing water and nutrients, exchanging gases, and providing a process for photosynthesis)
Many leaves contain a high proportion of hard-to-digest cellulose and relatively little energy. For this reason, folivorous mammals tend to have long digestive tracts and slow metabolisms. Many have the help of symbiotic bacteria to release the nutrients in their diets.
