Which term describes an animal with a single stomach?

• A. Monogastric
• B. Ruminant
• C. Herbivore
• D. Carnivore

Answer: (A)

Single-chamber stomach is the defining idea here. An animal described as monogastric has one stomach compartment, like humans, pigs, dogs, and cats. This contrasts with ruminants, which have a four-chamber stomach that allows foregut fermentation, seen in cows, sheep, and goats. Diet terms such as herbivore or carnivore talk about what the animal eats, not how its stomach is structured, though many herbivores can be monogastric or use other fermentation methods. So, the term for an animal with a single stomach is monogastric.
