  • 21-3 Ecology of Fungi
  • Saprobes

  • Lichens
    Lichens are symbiotic association between a fungus and a photosynthetic organism.
  • Mycorrhizae
    Mycorrhiza is the symbiotic association of plant roots and fungi.
  • Fungi as decomposers
    Fungi plan an essential role in maintaining equilibrium in nearly every ecosystem, where they recycle nutrients by breaking down the bodies and wastes of other organisms.
  • Fungi as parasites
    Parasitic fungi cause serious plant and animal diseases. A few cause diseases in humans.
  • Symbiotic relationships
    Some fungi form symbiotic relationships in which both partners benefit. Two such mutualistic associations, lichens and mycorrhizae are essential to many ecosystems.
