One example of beneficial symbiosis (or mutualism) is found between algae and the fungus of lichens. While fungi provide vital protection and moisture to algae, the algae nourish the fungi with photosynthetic nutrients that keep them alive. Another example of mutual symbiosis is the relationship which exists between the ocellaris clownfish that dwells among the tentacles of Ritteri sea anemones. The territorial fish protects the anemone from carnivorous fish, and in turn the stinging tentacles of the anemone protect the clownfish from its predators.
