Question

what are ruminants how do they digest cellulose​

Answer 1

Ruminants are mammals that are able to acquire nutrients from plant-based food by fermenting it in a specialized stomach prior to digestion, principally through microbial actions.

When plant material, such as grass, enters a cow's stomach, microorganisms immediately get to work to break it down. They do this with enzymes. Ruminants are unable to synthesise the enzymes needed to digest cellulose and other plant compounds.

Answer 2

Humans lack the enzyme necessary to digest cellulose. ... Ruminants have several stomachs that break down plant materials with the help of enzymes and bacteria. The partially digested material is then regurgitated into the mouth, which is then chewed to break the material down even further.
