2 Behavioral and physical characteristics that allow organisms to survive successfully in their environment are called….. Adaptations

3 Three Ways Animals Interact with their Environment Competition Predation Symbiosis

4 An interaction in which one organism kills another for food is called……. Predation

5 The struggle between two organisms to survive as they attempt to use limited resources is called… Competition

6 A close relationship between two species that benefits at least one of the species is called…… Symbiosis

7 Interaction in which one benefits and the other is not harmed…. Interaction in which both organisms benefit…… Mutualism Interaction in which one benefits and the other is harmed….. Parasitism Commensalism Symbiosis
