Symbiosis

/sim-bye-OH-sis/
🦋 Ecology●● Intermediate

Also known as: symbiotic relationship

An intimate ecological relationship between organisms of different species living in close physical association. The three main types are mutualism (both benefit), commensalism (one benefits, other unaffected), and parasitism (one benefits at the other's expense). Mycorrhizal fungi and plant roots are a classic mutualistic symbiosis.

Etymology

Greek symbiosis (living together), from syn (together) + bios (life)

Example

The symbiosis between mycorrhizal fungi and tree roots allows both organisms to thrive in nutrient-poor soils.
