Which of the Following are Important Adaptations Specifically to Herbivores

Question

Which of the following are important adaptations specifically to herbivores?
A) having a large, anoxic chamber where fermentation can occur and having an extended retention time for food
B) having a large, oxic chamber where fermentation can occur and having an extended retention time for food
C) having a large, anoxic chamber where fermentation can occur and having relatively rapid food passage through the digestive tract
D) having a large, oxic chamber where fermentation can occur and having relatively rapid food passage through the digestive tract

Accepted Answer

Herbivores have adaptations for digesting plant material, which is difficult to break down. A large, anoxic (oxygen-free) chamber for fermentation allows microorganisms to break down cellulose, and an extended retention time for food increases nutrient absorption.
