My Symbiosis Relationship

My symbiosis relationship is moss and a tree. My picture of moss on a tree was taken on the side of Crossroads South Middle School. It is an example of commensalism because only the moss benefits. The moss benefits because it needs moisture and sunlight to survive. Also, because it needs to now that it can obtain enough water and nutrients from the tree. Finally, this an example of commensalism because commensalism is when one organism benefits and the other organism is not harmed. That is what happened with the tree and the moss the moss benefited and the tree is not harmed.
