Answer:
B. Mutualistic bacteria in the hindgut of the termite digest the cellulose into sugars
Explanation:
Cellulose is a polysaccharide, cell walls of plant cells are made of cellulose. Termites eat cellulose and live on cellulose for their energy needs. Termites chew dead wood, but for its digestion termites depend on bacteria and protozoa which are present in their gut. They provide enzymes which can digest the cellulose of wood. Thus, they are in mutualistic relationship with termites. These microbes may starve ouside the termite body.
