Human: What is a symbiotic relationship, and what are some of the best examples of this? Assistant: 
A symbiotic relationship is one in which two organisms live together in a mutually beneficial relationship. The term "symbiosis" comes from the Greek word symbiontikos, meaning "living together". In biology, symbiosis refers to any close association between two different species that benefits both partners. Examples of symbiotic relationships include the relationship between ants and aphids, or between bees and flowers.
