Mistletoe and bromeliads both grow on trees. What relationship does each have with the tree that supports them?

Mistletoe - parasite/host relationship

Bromeliads - epiphyte/host relationship

Explanation:

Mistletoe is a parasitic plant. A parasite is an organism that grows on or live in another organism (the host), obtaining nutrients and other growth factors from the organism. Hence, mistletoe has a parasite/host relationship with whatever tree that supports it.

Bromeliads is known to be an epiphytic plant. An epiphyte is an organism that lives on another organism for support only. Epiphytes do not obtain their nutrients or any other growth factor from their hosts. Hence, bromedliads has a epiphyte/host relationship with whatever tree that supports it.
