Explain how termites are able to feed on wood.

Termite’s breakup the wood into tiny pieces using their sharp and strong mandibles which they swallow easily. On reaching the crop, protozoa in the crop ingest the swallowed food by phagocytosis. The secrete cellulose into their food vacuoles, thereby digesting the cellulose in the termites’ diet.

Some soluble products of digestion such as glucose diffuse out of the protozoa and are absorbed by the termite.
