Ruminants digest cellulose in their stomach because? Answer: They have microorganisms that digest cellulose

Ruminants digest cellulose in their stomach because they host symbiotic microbes (bacteria and protozoa) in a specialized chamber called the rumen. Since animals lack the specific enzyme required to break down cellulose, these microbes perform the fermentation, converting indigestible plant fibers into easily absorbed nutrients.
