Lichen

Lichen are symbiotic communities of vastly different organisms that have evolved intimately together for billions of years. The fungus provides shelter, water and nutrients. The algae provides energy in the form of sugar from photosynthesis. Just recently scientists discovered that most lichen have a third organism – a yeast – also living in symbiosis. Many of the 20,000 known species of lichen are miniature self-contained ecosystems.
