Ruminants, such as cows and sheep, have a specialized stomach with multiple chambers (not two, but four) that allows them to efficiently break down cellulose, a major component of plant cell walls, with the help of symbiotic microorganisms. This adaptation is crucial for their herbivorous diet, enabling them to extract nutrients from tough plant materials.
