Trimester 3 Final Exam Review Questions

population

A group of individuals that belong to the same species and live in the same area.

symbiosis

A relationship in which two different organisms live in close association with each other. Some of these relationships are good for both organisms (mutualism). Some of these relationships are good for one organism, but do not help or hurt the other organism (commensualism). Some of these relationships are good for one organism, but hurt the other organism (parasite-host and predator-prey).
