<h3>What is
disaccharide?</h3>
Any material made up of two simple sugar molecules (monosaccharides), coupled to one another, is referred to as a disaccharide, often known as double sugar.
A disaccharide (also known as a double sugar) is the sugar that results from the glycosidic connection of two monosaccharides (simple sugars). Disaccharides are water soluble, just as monosaccharides. The sugars sucrose, lactose, and maltose are three typical examples.
Disaccharides. Two monosaccharide units are joined by glycosidic linkages in either the or orientation to form disaccharides. Sucrose, lactose, and maltose are the three most significant ones.

More information is required to completely answer the question. Based on the experiment, feeding one group wood only and the other wood and antibiotics, the conclusion to be drawn is that the bacteria that lives in the gut of termites does not aid in digestion of the cellulose in wood.
Antibiotics only affect bacteria and so would leave the protozoa and the archaea in the gut of the termites. Both groups received the same amount of energy at the end of the experiment so it means that digestion is aided by either the protozoa or archaea and not bacteria.
