Final answer:
Termites are able to digest wood with the help of microorganisms in their stomachs that produce enzymes to break down lignin into carbohydrates.
Step-by-step explanation:
Termites are able to digest wood with the help of microorganisms in their stomachs. These microorganisms produce enzymes that break down the lignin in wood into soluble carbohydrate molecules that the termites can use as nutrition. This mutualistic relationship between termites and microorganisms allows termites to obtain energy from the cellulose in wood.
