What kind of symbiotic relationship is this.

The beautiful Bromeliad plants use their specialized roots to cling on to tree trunks and branches taking nothing but support from trees; drawing their water and nutrients from air and moisture that accumulates between their leaves like tiny little cups, storing water for later

This is an example of commensalism, where one species benefits (the Bromeliad plants) while the other is unaffected (the trees).
