What is the primary diet of termites?

Termites primarily feed on wood and cellulose, which is an organic polymer found in the cell walls of plants. This makes them particularly adept at breaking down and digesting materials that contain cellulose, such as wood, leaves, and other plant-based debris. Their ability to digest cellulose comes from symbiotic microorganisms in their gut, which help convert this tough material into simpler compounds that termites can use for nourishment.

Wood, being rich in cellulose, serves as an ideal food source for termites, allowing them to thrive in various environments, especially in forested and wooded areas. The other options, while they may represent food sources for some insects or organisms, are not relevant to termites. Hence, the significant focus on wood and cellulose accurately reflects the primary dietary habits and ecological role of these insects in breaking down plant material.
