Orchids feed on a micorrhizal fungus, which grows on the bark of certain trees. While it might be considered symbiotic, the orchid requires the trees it grows on to produce the fungus. The tree stays healthier due to orchids, however the orchids have no function nor biological reason or initiative to limit the growth of the fungus. The more fungus that can thrive within the tree will be beneficial to the orchids. Because of this dynamic the eventual death of the tree, due to the fungus that feeds the orchids, will allow the orchids to thrive to the point of propagation, spreading their seeds in the soil to reach the surrounding trees, which have a high probability of having the required fungus for them to feed. And this the process of death and rebirth continues from tree to tree, but the same line of orchids continue by jumping from corpse to corpse.
