Commensalism meaning

kə-mĕnsə-lĭzəm
The definition of commensalism is a relationship between two organisms where one is helped and the other is unaffected.

An example of commensalism is when a bird lives in a tree; the bird is helped by living in the tree because it has a place to build its nest and it is high up so protected from predators, but the tree is not affected.
