Different Diets of Herbivores

Cow

___________ cellulose well; no need to eat other sugars

Gorilla

___________ cellulose well; must add another sugar source, like fruit to diet

helpful bacteria
Helpful bacteria
  • How can cows digest cellulose?
    • bacteria live in their stomachs & help digest cellulose-rich (grass) meals

Eeeew…Chewingcud?
