How do termites use cellulose?

How do termites use cellulose?

Termites have protozoa and bacteria in their gut that allow them to break down the cellulose fibers in wood, which is difficult for other creatures to digest. These organisms turn those cellulose fibers into a nutritious meal and allow termites access to a food source that’s largely ignored by other species.

What is the symbiotic relationship between termites and cellulose digesting bacteria?

Not all termites consume cellulose, but those that do have a specialized midgut teeming with microbes (primarily protists, bacteria, and archaea) that break down the cellulose. The relationship between the termites and the microbes is a mutualism, because both species benefit from the relationship.

Do termites produce cellulose?

Cellulose. The food of termites is mainly cellulose, which is obtained from wood, grass, leaves, humus, manure of herbivorous animals, and materials of vegetative origin (e.g., paper, cardboard, cotton). Most lower termites and many higher ones feed on wood that is either sound or partly decayed.

What is the symbiotic relationship of termites?

In exchange, these organisms benefit from a continuous supply of energy-rich cellulose and a suitable environment in which to live. The relationship between termites and their endosymbionts demonstrates a symbiotic relationship of mutualism.

Do termites eat other termites?

If a termite, or several termites, become injured, then they become food for the rest of the able-bodied colony. During stretches of time when nitrogen containing food sources are low, extensive cannibalism occurs. In these cases even non-injured colony members are targeted for supper.

Why do termites digest cellulose?

Although termites can consume almost any cellulosic material, they cannot actually receive any nutrition without the help of symbiotic microorganisms living in their digestive tract. These bacteria, fungi and protozoa break down the cellulose and release nutrients that can then be absorbed by the host termite.

What happens in the relationship between termites and their gut protists?

The protists get a safe home in the termite’s gut and a continual supply of ingested wood. The termite is unable to digest cellulose by itself, so it uses the protists in its gut to do so. Both partners benefit from the symbiotic association, and that is what mutualism means.

Why can termites digest cellulose?

Digestion of Cellulose in Termites The rumen is the first compartment where ingested food containing cellulose is stored temporarily and later regurgitated to chew their cud. They are able to digest cellulose because of the presence of bacteria and enzymes in the rumen where anaerobic bacterial digestion occurs.

How do protists help termites?

What is the relationship between termites and trees?

While most termite species feed on dead wood, there are a few species that feed on live plants and trees. These termites weaken the limbs of the trees, which can cause heavy branches to break during storms. Eventually, the termite damage will be too extensive for the tree to survive.

Are termites carnivores?

Are Termites Carnivores, Herbivores or Omnivores? Termites are herbivorous creatures, so they eat organic plant matter. The insects dine on a blend of grasses, plants and woods. Some termite species are a threat to homeowners who have wooden houses.

Can termites eat humans?

Termites very rarely bite humans. While you may have an infestation of termites in your home, they don’t seek out humans or other living creatures like parasites, which feed from blood. Termites eat wood and other plant-based matter. A termite with the potential to bite you is the soldier, but again this is unlikely.

Can a termite Digest 40% of cellulose?

Wood contain 40 −50% cellulose. Most of the multicellular organisms can’t digests cellulose by their own. Termites also can’t do this by their own. So as there is solution to every query just like that there is also a solution to termite’s problem: Termites have special guests i.e certain endosymbiont microbes or bacteria & protozoans.

Where does a termite get its cellulase from?

Lower termites such as Coptotermes lacteus have Protozoa in their hindgut which produce a cellulase (s) quite distinct from that in the foregut and midgut. Comp. Blochem. Physiol.

What kind of symbiosis does a termite have?

(3) Some higher termites have a symbiosis with a fungus, Termitomyces, and Bacteroidetes and Firmicutes which thrive with a fungus-rich diet.

Which is the dominant microbiota in lower termites?

The dominant microbiota in lower termite hindguts are spirochaetes. (8) Higher termites do not have the protozoa that lower termites have in their hindguts that make cellulose digestion possible, so higher termites have evolved with different gut components and diets.
