Although termites can physically chew and ingest wood, they are incapable of chemically digesting cellulose into sugars. They rely on intestinal flagellates, e.g. Pyrrsonympha spp. and Trichonympha spp. which are capable of digesting cellulose into energy-rich sugar. These flagellates have shelter in the hindgut of termites and provide nutrition for them. They are not found anywhere else in nature. The example of termites and the flagellate microorganism best fit which symbiotic relationship?

• Parasitism.

• Predation.

• Commensalism.

• Mutualism.

• Invasive species.
