Unit 3 Test Review - Natural Selection

What is the advantage of having different shaped beaks?

• To look different from other species.
• To be able to eat the food readily available in the environment.
• To protect itself against predators.
• To protect itself against prey.

What is natural selection?

• a living individual that can carry out life processes

• Process by which an organism that better adapts to their environment survive and reproduce

• Process by which a community better adapts to their environment to give traits to one another within their generation.

• the time between when an organism is born and when they reproduce

Why do frogs and other organism reproduce so many eggs or offspring?
