Lichen is a composite organism consisting of algae and/or cyanobacteria and fungal filaments existing symbiotically. Its place in the grand scheme of things is probably not something it ponders. It likely doesn't ponder much at all, in fact.

It can be found across the globe, in some of the most extreme environments on Earth, and consists of a great many varieties and component species. If it should be attributed a purpose, much like any form of life, it would be to survive and thrive.

It achieves this admirably.
