Detailed explanation-1: -A monogastric is an animal with a single-compartmented stomach. Examples of monogastrics include humans, poultry, pigs, horses, rabbits, dogs and cats. Most monogastrics are generally unable to digest much cellulose food materials such as grasses.

Detailed explanation-2: -A monogastric organism has a simple single-chambered stomach (one stomach). Examples of monogastric herbivores are horses and rabbits. Examples of monogastric omnivores include humans, pigs, hamsters and rats. Furthermore, there are monogastric carnivores such as cats.

Detailed explanation-3: -In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds.

Detailed explanation-4: -The main differences between ruminants and mo-nogastrics are monogastrics only have one compart-ment to their stomach, whereas ruminants have four compartments: rumen, reticulum, omasum, and abo-masum.

Detailed explanation-5: -Monogastric herbivores show partial cellulose digestion. Ruminants or polygastric animals show complete cellulose digestion. Bacterial Action. Only the gut bacteria of monogastric herbivores can partially digest cellulose. The bacteria present in ruminants play a vital role in breaking cellulose.
