Protocooperation Protocooperation is a mutually beneficial relationship similar to that which occurs in mutualism, but in protocooperation, this relationship is not obligatory. Beneficial complementary resources are provided by each of the paired microorganisms. The organisms involved in this type of relationship can be separated, and if the resources provided by the complementary microorganism are supplied in the growth environment, each microorganism will function independently
