The algae increase the autotrophy by offering photosynthesis to the fungi in the lichen organism.
A lichen is an organism consisting of a symbiotic association between a fungus (the mycobiont) and algae. The mushroom brings water and mineral salts. The alga produces, by photosynthesis, various organic compounds of which it gives a part to the mushroom.
A lichen results from a relationship between a fungus and a
photosynthetic organism, which is based on mutualism. Algae is one of the
photosynthetic organisms, and it can provide a constant supply of food to the
fungus. The fungi provide a sheltered place for the algae to grow and reproduce.
