These beautiful Bromeliad plants use their specialized roots to cling 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. Is this an example of commensalism, mutualism, parasitism, or predation

This is an example of commensalism. In commensalism, one organism benefits while the other is neither harmed nor benefited. In this case, the Bromeliad plants benefit by obtaining support from trees and accessing water and nutrients from the surrounding environment, while the trees are unaffected by the presence of the Bromeliads.
