Answer the following question given this paragraph: 

Different diets require different types of digestive systems. Mammals that eat a carnivorous diet generally have a relatively simple digestive system. Their food consists mainly of proteins and fats that are easily and quickly digested. Herbivorous mammals, on the other hand, tend to have a more complicated digestive system. Complex plant carbohydrates such as cellulose are more difficult to digest. Some herbivores have more than one stomach. The stomachs store and slowly digest plant foods.


Q: Because complex plant carbohydrates such as cellulose are more difficult to digest, what animal diet is associated with a complicated digestive system?

 Choices:

- polyvore

- omnivore

- carnivore

- herbivore

A:
herbivore
