Quote en.wikipedia.org/wiki/Phoresy#…
In ecology, commensalism is a class of relationship between two organisms where one organism benefits without affecting the other. It compares with mutualism, in which both organisms benefit, amensalism, where one is harmed while the other is unaffected, and parasitism, where one benefits while the other is harmed.

Commensalism derives from the English word commensal, meaning "eating at the same table" in human social interaction, which in turn comes through French from the Medieval Latin commensalis, meaning "sharing a table", from the prefix com-, meaning "together", and mensa, meaning "table" or "meal".[1] Originally, the term was used to describe the use of waste food by second animals, like the carcass eaters that follow hunting animals, but wait until they have finished their meal.

Like all ecological interactions, commensalisms vary in strength and duration from intimate, long-lived symbioses to brief, weak interactions through intermediaries.

Phoresy is one animal attaching to another exclusively for transportation. This concerns mainly arthropods, examples of which are mites on insects (such as beetles, flies or bees), pseudoscorpions on mammals[3] or beetles, and millipedes on birds.[4] Phoresy can be either obligate or facultative (induced by environmental conditions).

Inquilinism is the use of a second organism for housing. Examples are epiphytic plants (such as many orchids) that grow on trees,[5] or birds that live in holes in trees.

Metabiosis is a more indirect dependency, in which one organism creates or prepares a suitable environment for a second. Examples include maggots, which feast and develop on corpses, and hermit crabs, which use gastropod shells to protect their bodies.
