describe the relationships between living organisms such as mutualism, predation, parasitism, competition, commensalism

In a mutualistic relationship, both species benefit.

Predation is when a predator eats another organism, in which the predator benefits and the other organism dies.

In competition, neither species benefits because they're too busy fighting over resources.

Commensalism is when only one of the two species benefits but the other is not harmed.
