Symbiotic.
The relationship between caribou and the bacteria in their stomachs is symbiotic (mutual).
We lack the enzyme cellulase... and we don't have bacteria in our stomachs that do like cows, only bacteria can digest cellulose.
Termites have adapted their stomachs so that they can extract cellulose from the soil humus.Mostly there is a symbiotic protozoa (metamonads) and other microbes in the termites stomachs that help them digest the cellulose.
They have cellulose-digesting, symbiotic microorganisms in chambers of their stomachs
Multi-chambered stomachs or "multiple stomachs.
They eat fruits seeds grasses bark and rutes, but also have a taste for meat. such as birds rodents and even the younge of large animals such as sheep or ANTELOPES.
There are several things that can break down cellulose. Most are anaerobic bacteria like cellulomonas and are found in the stomachs of cows and sheep.
no thay cant digest plastic thay also cant digest wood they have bacteria in there stomachs that digests it for them
Cows need to eat nearly all the time. There are "cud chewing" herbivores with a primary diet of grass. They have 4 stomachs and need to eat a lot of grass which passes between the stomachs to allow bacteria to break down the cellulose so that the cow can obtain the proteins and sugars it needs. When feeding hay or silage the cow needs a plentiful supply of these to keep its stomachs charged.
Ruminants are animals that eat grass. They are specially adapted to digest the cellulose found in grass by having large stomachs filled with fermenting bacteria.
Ruminant animals have 4 stomachs but the microbed don't produce cellulose, they break it down.
Not ALL herbivores do, four chambers are a characteristic of "ruminant" herbivores. Herbivores need to be able to get energy from plant material (a sugar called cellulose) and to do this they need to get bacteria to "ferment" the plant material they eat (they then live on the reproducing bacteria). The chambers of the stomach are where this fermentation happens. Humans stomachs are designed to eat fruits and meat and therefor we do not need large stomachs (gorillas do because although they are not ruminants they live on plants).
