A student was asked to model different relationships between organisms. She used the example of an oak tree and Spanish moss in the picture below to show one of these relationships. The Spanish moss uses the oak tree for support but makes its own food and gets its water from the air. The oak tree receives no benefit but is generally not harmed by the Spanish moss. What type of relationship does this best represent?

mutualism
parasitism
competition
commensalism
