Parasitism is when one organism lives inside another organism and feeds off of it, killing it slowly. For example when a tick lives in a dog.

Predation is when one organism eats another to survive. For example a snake eats a rat.mig_predation_eusthenopteron_g.jpg
Mutualism is when both organisms benefits from the interaction. For example a flower and a bee.beeFlowerCassino.jpg
