Behavioral and physical characteristics that allow

organisms to survive successfully in their environment are

called…..

Adaptations

Page 3: Science Review Section 1 Interactions Among Living Things.

Three Ways Animals Interact with their Environment

Competition

Predation

Symbiosis

Page 4: Science Review Section 1 Interactions Among Living Things.

An interaction in which one organism kills another for food is

called…….

Predation

Page 5: Science Review Section 1 Interactions Among Living Things.

The struggle between two organisms to survive as they

attempt to use limited resources is called…

Competition

Page 6: Science Review Section 1 Interactions Among Living Things.

A close relationship between two species that benefits at least one of

the species is called……

Symbiosis

Energy Roles in an Ecosystem

• Producer

• Consumer

• Decomposer

Page 16: Science Review Section 1 Interactions Among Living Things.

Producers

• Plants

• Algae

• Bacteria

Page 17: Science Review Section 1 Interactions Among Living Things.

Consumers

• Herbivore– Plant eaters

• Carnivore– Meat eaters

• Omnivore– Plant and meat eaters

• Scavenger– Eat dead organisms
