Adaptations

• What must an organism do to survive?

  Adapt to its environment
• How does a polar bear adapt to cold?

  It has thick fur for insulation
• What adaptation helps owls see in the dark?

  Big eyes for better night vision
• Into how many groups do scientists categorize adaptations?

  Three groups
• What are the three groups of adaptations?

  Structural, behavioral, and functional
• What are structural adaptations?

  • Physical features of an organism
  • Examples: shape, color, body structure
• What are behavioral adaptations?

  • Ways organisms act or behave
  • Examples: migration, cooling behaviors
• What are functional adaptations?

  • Internal processes of an organism
  • Examples: metabolism, reproductive systems
• Why do seals and walruses have a rounded shape?

  To conserve body heat in cold environments
• How does the gray-brown color of seals help them?

  It camouflages them from predators
• What do elephants do to cool down in hot environments?

  Flap their ears and spray water
• Why do swallows migrate during winter?

  To avoid cold and lack of food
• How do desert animals conserve water?

  By producing little sweat and concentrated urine
• What do camels do to release water?

  They have strong muscles
• What is hibernation in brown bears considered?

  A behavioral and functional adaptation
• How do brown bears prepare for hibernation?

• What are extremophiles?

  Microorganisms adapted to extreme environments
• Where can extremophiles live?

  Hot springs, salt lakes, deep sea vents
• What did astronauts find in 2017?

  Bacteria on the International Space Station
• How do structural adaptations differ from behavioral adaptations?

  Structural adaptations are physical features
• How do functional adaptations relate to an organism's survival?

  They involve internal processes for survival
