A symbiotic relationship is one in which two different species live together interdependently. An example of a symbiotic relationship is the relationship between lichens and algae, where the alga provides nutrients to the lichen, while the lichen provides protection for the algae. Other examples include the relationship between termites and fungus, or the relationship between ants and aphids.
