A lichen is structurally organised entity consisting of the permanent association of a fungus and an alga. Algae prepare food for fungi. Fungi provides shelter and absorbs water and minerals for algal partner. Lichens are very sensitive to air pollution, particularly to SO2 concentration in the atmosphere. They die at higher levels of SO2.
