Why are the bacteria in a termite’s stomach considered mutualistic and not parasitic?

The bacteria in a termite's stomach are considered mutualistic because they have a symbiotic relationship with the termite that benefits both parties. The bacteria help the termite digest cellulose, which is a tough compound found in the wood that termites feed on. In return, the bacteria get a constant source of food and a safe environment to live in. This mutualistic relationship is beneficial for both the termite and the bacteria, as the termite is able to efficiently digest its food and the bacteria have a stable home and food source. This is different from a parasitic relationship, where one organism benefits at the expense of the other.
