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
Regents Biology
Helpful bacteria
 How can cows digest cellulose?

bacteria live in their stomachs & help digest
cellulose-rich (grass) meals
Eeeew…
