Lichens are formed by Association of a fungus and an alga. The relationship that these individuals establish is a symbiosis, i.e., a relationship where the two obtained a benefit with this Association. Algae carried out photosynthesis, so it provides organic matter to the fungus. The fungus captures water and mineral salts of the environment where you live, by dry be and gives protection to the alga against desiccation.
