What is the primary diet of drywood termites?

The primary diet of drywood termites consists of wood. These termites are specially adapted to consume cellulose, which is the main constituent of wood. Their digestive system hosts symbiotic microorganisms that help break down the cellulose, allowing them to extract nutrients efficiently from the wood they consume. Drywood termites typically infest dry, sound wood that has not been in contact with soil, often nesting within the wood itself and creating galleries as they consume it.

Other options do not accurately reflect the feeding habits of drywood termites. While some insects may consume leaves or organic matter from the soil, this is not characteristic of drywood termites, who specifically require wood as their primary food source.
