What is a 5 symbiotic relationship?

Excuse me, could you please clarify what exactly is meant by a "5 symbiotic relationship"? Is it a specific term used in a particular field, such as biology or finance? As I understand it, symbiosis typically refers to a relationship between two different organisms where both benefit from their association. However, the addition of the number "5" seems to suggest a more complex or specific scenario. Could you provide some context or further explanation to help me better understand what you mean?
