Fungi: Lichens

Lichens are unique organisms formed by a symbiotic relationship between an alga or blue-green bacterium and a fungus. The alga or bacterium performs photosynthesis, providing nutrients to the fungus, which in turn offers water, elements, and protection. Lichens are diverse, thriving in harsh environments like the Arctic, serving as food for animals, and playing a crucial role in soil formation by breaking down rocks.
