There could be more than two organisms in the relationship.There a three types of symbiotic relationships. They are commensalism, when one organism benefits and the other is not harmed. Mutualism is when both organisms in the relationship benefit. The last relationship is parasitism, when one organism benefits and the other is harmed. An example of commensalism is ivy and a tree.
