In ecology I have learned about mutualism, which is when both organisms benefit in a relationship.Commensalism which is when one organism benefits and the is not harmed.Parasitism which is when one organism benefits and the other is harmed.Adaptation is how an animal adapts to an ecosystem.Parasite is an organism that harms other organisms in which the parasite benefits.Niche is the organism’s job in the community A decomposer is an organism that decomposes other organisms after they are dead.A host is the parasite’s victim in which it is harming and the other is benefiting.An ecosystem is the area in which the organisms inhabit.That is a part about what I have learned about ecology this year.
