Why don't termites break cellulose?

Termites don't break down cellulose on their own; instead, they rely on symbiotic microorganisms, such as bacteria and protozoa, in their guts to digest cellulose. These microorganisms produce enzymes called cellulases that can break down the complex cellulose structure into simpler sugars. This mutualistic relationship allows termites to efficiently convert cellulose from wood and plant material into energy, enabling them to thrive on a diet primarily composed of these tough organic compounds. Without these microorganisms, termites would be unable to utilize cellulose as a food source.
