Functional caecum
Actually ruminants cannot digest cellulose, they have symbiotic bacteria in a part of their stomach called a "rumen" digest the cellulose down to sugars and starches that the ruminants can actually digest in another part of their stomach later.
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.
The organ that helps a rabbit to digest is stomach.
Herbivorous mammals don't secrete the enzymes required to digest cellulose. They sub-contract the work of cellulose digestion to guest bacteria. The bacteria are provided with a home and lots of food in exchange. Humans don't do this. We have no capacity to digest cellulose. The appendix is the remnant of the Caecum in the human.
By taking a sample of fluid from the cows stomach, making a culture of microorganisms present there, placing the culture in a medium that contains cellulose, waiting, testing for glucose at intervals under conditions that are similar to the cow's body temperature, pH, etc.
Ants cannot digest cellulose. Termites can, but only because of symbiotic microorganisms in their digestive system. Termites are sometimes called white ants but they belong to a completely different insect order.
People cannot digest cellulose
the appendix digest cellulose, but human appendix does not work.
no animal is capable of digesting cellulose which is a plant product. Why because no enzymes to digest the cellulose are present in the animals digestive system. So termites adopt the tryconympha in their digestive system. In us also, most of the plant material we eat is not digested. In animals like cows and buffaloes, the grass is soaked in the water in the stomach so as to make digestion of cellulose easy for microorganisms inside the intestine.
The rat's diet can be inferred by the composition of microorganisms in its caecum. The associated structures are built to function based on its specific diet.
None. Humans can't digest cellulose. Bacteria in the large intestine can digest some cellulose, creating gas and vitamin K.
The digestive system of ruminants consists of four stomach.
