What do you call animals that digest food in a single-compartment stomach?

• A. Ruminants
• B. Monogastrics
• C. Herbivores
• D. Suids

Answer: (B)

Animals that digest food in a single-compartment stomach are referred to as monogastrics. This classification is primarily based on their digestive anatomy and physiology. Monogastric animals, such as pigs, dogs, and humans, have a straightforward digestive system consisting of just one stomach compartment. This system is designed for the processing of a variety of feedstuffs, allowing for the efficient breakdown and absorption of nutrients.

In contrast, ruminants, which have a multi-compartment stomach, engage in a unique process called rumination, where they regurgitate and re-chew their cud to facilitate the digestion of fibrous plant material. Herbivores encompass both monogastrics and ruminants, as it is a broader term describing animals that primarily consume plant-based diets. Suids specifically refer to the pig family, which predominantly consists of monogastric animals, but the term is more specific than the general classification of monogastrics. Therefore, monogastrics is the correct term for animals with a single-compartment stomach.
