Unit 4 Lesson 6 What Are Physical and Behavioral Adaptations? A characteristic that helps a living thing survive is called an adaptation. Copyright © Houghton Mifflin Harcourt Publishing Company 3

Unit 4 Lesson 6 What Are Physical and Behavioral Adaptations? Animals that survive better because of a new characteristic are more likely to reproduce and pass that characteristic on to their young. The adaptation becomes more common in the population. In this way, populations of plants and animals become adapted to their habitats. Copyright © Houghton Mifflin Harcourt Publishing Company 4

Unit 4 Lesson 6 What Are Physical and Behavioral Adaptations? If animals have similar habitats, they share similar adaptations. Copyright © Houghton Mifflin Harcourt Publishing Company 5

Unit 4 Lesson 6 What Are Physical and Behavioral Adaptations? On Your Best Behavior The way living things act is called behavior. Some behaviors are adaptations that help animals survive. Behaviors that animals know how to do without being taught are called instincts. Copyright © Houghton Mifflin Harcourt Publishing Company 20

Unit 4 Lesson 6 What Are Physical and Behavioral Adaptations? The Circle of Life Living things go through stages of growth and development called a life cycle. A living thing’s life cycle is related to its habitat. Because of this, differences in life cycles are a type of adaptation. Copyright © Houghton Mifflin Harcourt Publishing Company 27

Unit 4 Lesson 6 What Are Physical and Behavioral Adaptations? Living Things Change Every organism is slightly different from every other organism. For example, corn snakes come in many colors and patterns. Their survival can depend upon their color and whether their predators can see them. If the predator cannot see the snake, they are more likely to survive and produce more offspring with the same coloring. Copyright © Houghton Mifflin Harcourt Publishing Company 34

Unit 4 Lesson 6 What Are Physical and Behavioral Adaptations? Living Things Change Sometimes living things change because their environment changes. For example, bacteria have changed with the discovery of antibiotics that kill them. The first antibiotic, penicillin, saved lives. Some bacteria resist penicillin, however, and survive and multiply. Researchers must find new antibiotics to kill the resistant bacteria. Copyright © Houghton Mifflin Harcourt Publishing Company 35
