Which of the following is a primary component that termites feed on?

Termites primarily feed on wood due to its high cellulose content, which is their main nutritional source. Cellulose is a complex carbohydrate that is difficult for many organisms to digest, but termites have specialized microorganisms in their guts that help break down cellulose into simpler substances that they can absorb. This ability allows termites to thrive on organic materials like wood, leaves, and other plant matter.

While termites are known for their wood-eating habits, the other materials listed, such as plastic, metal, and concrete, do not provide the necessary nutrients that termites require for survival. Therefore, they do not serve as food sources for these insects. Understanding the dietary needs of termites is crucial for effective pest management and control strategies, particularly in ensuring that structures and materials made from wood are protected from potential infestations.
