Mutualistic symbiosis, also known as mutualism, is a scientific concept that refers to long-term, mutually beneficial relationships between two organisms.

A common example: the relationship between flowers and their pollinators — like bees. Bees gather pollen and nectar from flowers for their own use. They also spread the flower’s pollen far and wide, helping it reproduce.
