Termites primarily feed on which type of material?

Termites primarily feed on wood because they are cellulose-eating insects, and cellulose is a key component found in the structure of plants and trees. Wood is rich in cellulose, making it an ideal food source for termites. They have specialized microbes in their gut that help them digest this complex carbohydrate. This ability to break down cellulose allows termites to extract the necessary nutrients for their survival.

Other materials listed, such as plastic, metal, and glass, do not contain cellulose and are not digestible by termites. Thus, these materials cannot provide the necessary nutrients that termites need to thrive, reaffirming that wood is their primary food source.
