In commensalism, how does the relationship between the organisms operate?

In commensalism, one organism benefits while the other is neither harmed nor helped. This type of symbiotic relationship exemplifies how certain species can interact within an ecosystem where the presence of one species can provide advantages to another, without any negative consequences for the latter.

For example, birds may nest in trees; the tree offers a habitat and protection for the bird while the tree itself does not derive any benefit or harm from this interaction. This illustrates the essence of commensalism, highlighting the balance that can exist in ecological relationships.

The nature of commensalism ensures that while one species enjoys advantages such as shelter or transportation, the other continues its existence unaffected by this relationship.
