Q: Where is roughage fermented and digested in pseudo-ruminants? Read this paragraph and choose the correct option from the provided answers: Pseudo-ruminants Some animals, such as camels and alpacas, are pseudo-ruminants. They eat a lot of plant material and roughage. Digesting plant material is not easy because plant cell walls contain the polymeric sugar molecule cellulose.

Therefore, the digestive system must be able to handle large amounts of roughage and break down the cellulose. Pseudo-ruminants have a threechamber stomach in the digestive system. However, their cecuma pouched organ at the beginning of the large intestine containing many microorganisms that are necessary for the digestion of plant materialsis large and is the site where the roughage is fermented and digested. These animals do not have a rumen but have an omasum, abomasum, and reticulum. Choices: - in their ileum - in their appendix - in their pancreas - in their cecum A:
