Describe the symbiosis between wood-boring bivalves and the bacteria inhabiting their guts. How do both organisms benefit from the relationship?

What will be an ideal response?


This is a mutualistic relationship. The bivalves have long guts that also contain certain cellulose-digesting bacteria. These adaptations aid in digesting wood. The bacteria have a protected home in the animal's intestinal tract, while the bivlaves get an energy source from the action of the bacterial enzymes on the wood.
