Organisms have different types of behaviors. Some of these behaviors are

natural responses called instincts. Other behaviors are learned through

the use of an organism’s senses through interactions with the environment.

Which three behaviors are examples of instincts?

•  birds returning to a bird feeder for food

• monkeys using tools

• ants living in a colony

• sea turtles swimming

• geese flying in a group

The picture shows two mice called pocket mice. Pocket mice can be born

with either light-colored fur or dark-colored fur. A group of pocket mice

lives in a habitat where there is light sandy soil and dark lava rocks. Mice

with light-colored fur blend in with the light sandy soil. Mice with

dark-colored fur blend in with the dark lava rocks.

Which habitat change would most likely benefit mice with dark-colored

fur and not help mice with light-colored fur?

• Dark lava rocks break into small pieces from weathering.

• Light sandy soil becomes very dry because of direct sunlight.

• Lava erupts from a volcano and then hardens into large areas of dark lava

  rocks.

• Light sandy soil blows around in the wind and covers up dark lava rocks.

than an animal with light-colored fur?

• a desert that has deep sand and only a few plants

• a tundra that has snow covering the ground and no growing plants

• a mountain region that has evergreen trees spread far apart
