What can fabric insects digest to utilize as an energy source?

• A. Cellulose
• B. Keratin
• C. Chitin
• D. Starch

Answer: (B)

Fabric insects, also known as fabric-dwelling insects, primarily rely on keratin as a source of energy. Keratin is a fibrous structural protein found in hair, nails, feathers, and the outer layer of skin in many animals. These insects have developed specialized enzymes to break down keratin, enabling them to utilize this protein as an energy source. This unique ability allows them to thrive in environments where other forms of organic matter might not be readily available. The other options do not serve as suitable energy sources for fabric insects. Cellulose is primarily digested by organisms equipped with specific enzymes, such as certain bacteria and fungi, which fabric insects do not possess. Chitin is a major component of the exoskeletons of arthropods, and while some insects can digest chitin, it is not a primary energy source for fabric insects. Starch is a carbohydrate that is typically broken down by other types of organisms that have the necessary enzymes but is not relevant to the diet of fabric insects. In summary, the dietary preference of fabric insects for keratin reflects their evolutionary adaptation to their niche, distinguishing their metabolic processes from those of other insect species.
