What is the name of the symbiotic relationship in which one species benefits while the other species is not affected?

Answer 1

commensalism

Commensalism is a symbiotic relationship in which one species benefits while the other species is not affected. One species typically uses the other for a purpose other than food. For example, mites attach themselves to larger flying insects to get a free ride.  Hermit crabs use the shells of dead snails for homes.
