In commensalism, how do the two organisms interact?

In commensalism, one organism benefits from the relationship while the other organism is neither helped nor harmed. This type of interaction can be illustrated by examples such as barnacles attaching to a whale. The barnacles benefit by getting access to food and mobility, while the whale is largely unaffected by their presence.

This relationship is distinct because it involves an asymmetrical interaction, where the positive impact on one organism does not impose any negative effects on the other. It highlights the complexity of ecological relationships, demonstrating that not all interactions in nature are mutually beneficial or harmful. Understanding this concept is essential for studying biological diversity and the various ways organisms can coexist in an ecosystem.
