their intestinal tract contains cellulose-hydrolyzing microorganisms
Cows are able to utilize more from the cellulose than pigs are, because cows have a digestive system that enables them to break down the cellulose into smaller pieces through the process of fermentation. Pigs, on the other hand, are not ruminants (which cows are), but are monogastrics, and cannot efficiently utilize cellulose like cows can. So, essentially, cellulose will simply "pass through" the system without much being taken away from it.
Mutualism because both the cow and the bacteria are benefitting. The bacteria is benefitting because it gets energy from digesting the cows' cellulose. The cow is benefitting because it is getting its cellulose digested for it.
No, cannot break one of the beta bonds connecting the units of cellulose. Ruminants (e.g. cows, sheep) can however digest cellulose in their rumen, not themselves but because of the complex microorganisms living in their rumen.
yes
Cellulose
people cannot digest cellulose but cows can
people cannot digest cellulose but cows can
The cell walls of plants are made of cellulose. Approximately 33 percent of all plant material is cellulose. Humans cannot digest cellulose, but animals such as cows and horses can digest cellulose for food.
Eating grass
Cows do not digest cellulose cell walls because they, as an animal, are incapable of producing a special enzyme, called cellulase, to do the job. The cellulose-digesting bacteria in their rumen, however, are capable of producing such an enzyme and are thus responsible for digesting cellulose and helping the cow obtain essential nutrients from coarse plant material where she cannot.
Decomposers give cows nutrients to live
Inside the termites digestive tract, there is a symbotic microorganisms by the name of Trichonympha sphaerica who also has a symbiotic microorganism inside of it that digest the cellulose so that the termite can eat it. For cows it is the same they have symbiotic microorganisms inside of them that breaks down the cellulose but I am uncertain of the name.
