Do termites primarily feed on materials containing cellulose?

Termites are known for their diet that primarily consists of cellulose, which is a complex carbohydrate found in the cell walls of plants. This substance is abundant in materials such as wood, paper, and certain types of vegetation. The ability of termites to digest cellulose is due to the specialized microbes and protozoa in their gut that help break down this tough material into usable nutrients.

The reason that the correct answer asserts that termites primarily feed on cellulose is rooted in their biological and ecological role as decomposers. By breaking down cellulose, termites contribute to nutrient cycling in ecosystems, helping to recycle dead plant material back into the soil. This not only nourishes the soil but also supports plant growth, making termites an important component of their habitats.

The other choices present limitations that do not reflect the feeding habits of termites. For instance, suggesting that termites only feed during the winter or under specific dry conditions misrepresents their feeding behavior, as they are active throughout the year and can thrive in various moisture levels. Additionally, stating "No" overlooks the fundamental aspect of their diet, thereby missing the key characteristic that defines them as a species.
