Adaptations

• Why does an organism need to adapt to its environment?


  To be able to survive
• What are the three types of adaptations?

  • Structural adaptations
  • Behavioural adaptations
  • Functional adaptations
• What are structural adaptations?

  Physical features like shape and colour
• How do walruses and seals adapt structurally?

  They have a round shape to store fat
• Why do walruses and seals have low surface area to volume ratio?

  To conserve body heat
• What are behavioural adaptations?

  Ways an organism behaves
• How do elephants cool themselves down?

  They spray water and flap their ears
• What are functional adaptations?

  Processes inside an organism
• How do desert animals adapt functionally to preserve water?

  They produce little sweat and concentrated urine
• What do camels store in their humps?

  Fat
• How do camels use the fat stored in their humps?

  They break it down to release urine
• What are extremophiles?

  Microorganisms adapted to extreme environments
• What types of extreme environments can extremophiles live in?

  High temperatures, high salt concentrations, high pressures
• Where can extremophiles be found?

  Hot springs and salt lakes
• How do extremophiles survive in high-pressure environments?

  They are adapted to withstand extreme conditions
