d. Birds and mammals
<Understand>
9. How the digestive system differs between herbivores and carnivores?
a. Herbivores have less parts than carnivores since their food is easier to
digest.
b. Herbivores have a four chambers stomach and a large small intestine while
carnivores have a single stomach and a short small intestine.
c. Carnivores have a single stomach and two large intestines while herbivores
have a short small intestine with a single stomach.
d. Carnivores have a four chambers stomach and a short large intestine while
herbivores have four chambers stomach and a short small intestine.

10. Why do you think birds need a proventriculus and a gizzard ?
a. Because normally, they eat while they fly, so they need these parts inside
the beak to chew the food faster.
b. Because one is necessary to receive the food and the other to excrete it.
c. Due to their lack of teeth, they need more parts to store and break down
food into smaller particles.
d. The proventriculus is needed to chew food such as grains and seeds, while
the gizzard is used to chew meat.
