Adaptiations

• Animal adaptations STRUCTURAL


  Predators:

  • sharp teeth
  • claws, speed
  • forwards facing eyes

  Cold:

  • camouflage
  • small surface area : volume (less heat lost via radiation)
  • thick skin, small ears

  Hot:

  • camouflage
  • large surface area : volume (more heat lost via radiation
  • large ears
• Animal adaptations BEHAVORIAL

  Predators:

  • pack hunting

  Cold:

  • hibernation
  • huddling in packs

  Hot:

  • working during the early hour - when temperature is lowest
  • desert ants - long legs to avoid contact with the sand
• Animal adaptations FUNCTIONAL 


  Cold:

  • lower metabolism (less eating)

  Hot:

  • very concentrated urine - less water lost, don't need to drink a lot
  • camels store water in their humps
• Plant adaptations

  Light:

  • taller
  • broader
  • more chlorophyll
  • flower when light available

  Water:

  E.g. cactus

  • wide reaching, shallow roots
  • small surface area - leaves reduced to spikes

  Space:

  • speed dispersal
  • propellers (wind)
  • attractive fruit (animals)
  • float (water)
• Extremophiles

  • organisms that live in extreme conditions to avoid competition
