Science Ecology Review Terms Goal: Review the following terms for a vocabulary assessment on Friday.

Organism Definition: An animal

host Definition: the organism that a parasite lives in or on

parasite Definition: The organism that lives in or on another organism and harms it.

Predator Definition: The organism that does the killing in a predation interaction.

Prey Definition: The organism that is killed and eaten in a predation interaction.

Predation Definition: A relationship in which one organism kills another for food.

Parasitism Definition:A relationship in which one organism lives in or on another animal and harms it!!

Mutualism Definition: a relationship between two species (types of animal) in which both species benefit (get something).

Niche Definition: The role of an organism in its habitat (its job).

Competition Definition: The struggle between organisms to survive as they both use the same limited resources.

Natural Selection Definition: The process by which characteristics that help an animal in its environment become more common.

Adaptation Definition: a behavior or physical characteristic that allows an organism to successfully live in its environment.

Symbiosis Definition: a close relationship between two species in which at least on of them benefits (gets something)

Commensalism Definition: a relationship in which one organism benefits (gets something), but the other is not helped or harmed.
