In which type of creatures would you find a ruminant?

Cattle are classified as ruminants, which are a specific group of mammals that primarily herbivorous and are characterized by their unique digestive system. This system includes a multi-chambered stomach, which allows them to efficiently break down tough plant materials like cellulose found in grasses. The four distinct compartments of a ruminant's stomach—namely the rumen, reticulum, omasum, and abomasum—enable the fermentation and digestion of food, making it possible for these animals to extract nutrients from fibrous plant matter effectively.

Ruminants are also known for the behavior of rumination, where they regurgitate food from the first stomach chamber back into their mouths to chew it again, aiding in the digestion process. This adaptation is vital for cattle and other ruminants as it allows them to thrive on a diet that many other animals might find challenging to digest.

The other options, such as rodents, birds, and reptiles, do not possess this specialized digestive system. Instead, rodents have continuously growing incisors and adapted digestive systems suited for their grain and plant-based diets, birds typically have a crop and gizzard for grinding food, and reptiles may have simpler stomachs designed for their varied diets, but none
