Fungi are found worldwide in a vast range of habitats. They predominantly grow in terrestrial environments such as soil, dead organic matter, and in symbiotic relationships with plants, animals, or other fungi. They can also be found in aquatic habitats, including clean freshwater, slightly brackish water, and even in deep-sea sediments. Fungi are remarkably adaptable, living in extreme environments like deserts, polar regions, alpine areas, and places with high salt concentrations or ionizing radiation. They are also present in urban settings, on plants, inside animals, and even on and within humans. Some fungi live as parasites on plants or animals, while others form symbiotic relationships such as lichens with algae or cyanobacteria. Overall, fungi are nearly everywhere-from soil and forests to streams, glaciers, and the sea bed
