The 4 types of symbiosis

Mutualism - where both parties benefit

Commensalism - where one party is not impacted while the other is benefited

Parasitism - where one party is harmed and the other is benefited

Communism - where both parties are harmed

When two organisms mutually benefit, it's called "symbiosis"

When only one organism benefits, it's called "parasitism." When neither benefits, that's called "marriage."
