Termites on an eroded piece of wood. Termites, also called
white ants, belong to the oldest state-forming insects.
Most of the termites feed on wood, but they can not digest the wood by themselves. Particles, roughly hackled by special mouth tools, reach a stomage tainted with chitine tooths through a crop. For some species the release of cellulose degrading enzymes has been demonstrated. However, the mayor part of the digesting process is done by protists (mainly flagellates), bacteria and yeasts.
