Commensalism in ecology refers to a symbiotic relationship where one organism benefits while the other neither gains nor suffers. This interaction is part of a broader spectrum of symbiotic relationships, including mutualism and parasitism. Examples of commensalism range from mites using insects for transport to epiphytic plants growing on trees. The concept is crucial for understanding the dynamics of ecosystems and the evolution of species interactions.
