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.

Commensalism

Mutualism

Parasitism

Predation

Commensalism - The relationship between the Bromeliad plants and the tree they cling to is an example of commensalism, as the Bromeliad benefits from the tree for support, while the tree is unaffected by the presence of the Bromeliad.
