adaptations

    Cards (6)

    • Adaptations for survival:
      • Organisms must be adapted to their environment to survive
      • Adaptations can be structural, behavioral, or functional
    • Structural adaptations:
      • Physical features like shape or color
      • Example: Seals and walruses have a rounded shape, store fat, and have a low surface area to volume ratio to conserve body heat
      • Gray-brown color helps camouflage them from predators
    • Behavioral adaptations:
      • Way an organism behaves or acts
      • Example: Elephants flap ears and spray water to cool down in hot environments
      • Swallows migrate to warmer countries during winter to avoid cold and lack of food
    • Functional adaptations:
      • Processes inside an organism's body like metabolism or reproductive system
      • Example: Desert animals conserve water by producing little sweat and concentrated urine
      • Camels accumulate fat in humps to release water later
    • Brown bears (Ursus actos) adaptations:
      • Found in northern latitudes, indicating adaptation to cold environment
      • Thick fur for insulation is a structural adaptation
      • Diverse diet includes plants, fungi, fish, invertebrates, and mammals like deer
      • Adapted to catch different prey with long sharp claws for fish and strong muscles for deer, both structural adaptations
      • Hibernate in winter to conserve energy, lowering metabolism, a functional adaptation
    • Extremophiles:
      • Microorganisms adapted to extreme environments
      • Can live in high temperatures, high salt concentrations, and high pressures
      • Example: Bacteria found on the outside of the International Space Station
