How to use symbiosis

Symbiosis originally refers to a biological arrangement where two organisms live together in a mutually beneficial or at least non-harmful relationship, but it is widely used metaphorically in business, social, and interpersonal contexts to describe any interdependent partnership. The term emphasizes balance and mutual benefit, distinguishing it from one-sided relationships like parasitism.
