What is an Commensalism relationship in the desert?

Commensalism is a type of symbiotic relationship where one organism benefits while the other is neither helped nor harmed. In desert ecosystems, an example of commensalism could be seen with epiphytic plants, like certain types of moss or lichen, that grow on cacti. These epiphytes gain a place to live and access to moisture without affecting the cactus, which remains unaffected by their presence. This relationship highlights the adaptations of organisms to thrive in harsh desert conditions.
