Which symbiotic relationship describes one species benefiting while the other is unaffected?

Explanation:
Commensalism is a relationship where one organism benefits and the other is largely unaffected. For example, barnacles attaching to a whale gain a hidden advantage by being transported to nutrient-rich waters, while the whale experiences no meaningful harm or benefit. This differs from mutualism, where both organisms benefit; parasitism, where one benefits at the expense of the other; and predation, where one species kills and consumes the other.
