What is one adaptation of drywoods with respect to wood consumption?

The correct answer highlights that drywood termites exhibit a preference for sapwood because it tends to be more moisture-rich and easier for them to digest compared to heartwood. Sapwood, which is the younger, outer layers of wood, is typically less dense and contains more nutrients. This makes it a more suitable food source for drywood termites, which rely heavily on the cellulose found in wood for their sustenance.

In contrast, heartwood is often less desirable for these insects due to its denser composition and lower moisture levels. While drywood termites can consume heartwood, their feeding habits indicate a clear affinity for the easier-to-process sapwood. This adaptation is crucial for their survival, as it allows them to efficiently utilize the resources available within their habitat.
