Question

3. Herbivores do not produce enzymes that digest cellulose. How does the cellulose in their
food get digested?
1. Algae in their gut convert the cellulose into simple sugars.
ii. Bacteria in their gut convert the cellulose into glucose.
ii. Viruses in their gut convert the cellulose into simple sugars.​

Answer 1

All herbivores eat grasses and other plant material. Plants contain cellulose, which is very hard to digest. So, when a herbivore swallows some grass, the chewed grass first enters the compartment of the stomach called the rumen. The rumen contains a salty solution and bacteria that helps to break down the cellulose.
