Which characteristic is typical of ruminants?

• A. Single-chambered stomachs
• B. Short alimentary canals
• C. Enlarged multichambered stomachs
• D. Flat teeth for grinding

Answer: (C)

Ruminants digest fibrous plant material through foregut fermentation, which requires a large, multi‑chambered stomach. Their stomach is divided into four compartments—the rumen, reticulum, omasum, and abomasum—so microbes can break down cellulose before the food moves to the true stomach for digestion. This enlarged, four-part stomach is the hallmark that lets them extract energy from tough plant material and even chew cud to further break down fiber. That’s why the best description is an enlarged multichambered stomach. While other traits like a single-chambered stomach (found in many nonruminant animals), a short alimentary canal, or flat grinding teeth can occur in herbivores too, they don’t define the ruminant digestive strategy the way a four‑section, enlarged stomach does.
