Adaptations

• What is meant by a structural adaptation?

  A structural adaptation refers to an adaptation of the body shape or structure
• What conditions do Camals live in?


  Hot + dry
• What is structural adaptation in animals?

  Adaptation of body shape or function
• What is a hump?

  A store of fat, thermal insulator

  allows heat loss from other parts of the body reducing water loss from sweating
• Why do Camels have a thick coat?

  Camels have a thick coat on upper surface of the body which is insulated from the sun and reduces water loss from sweating
• Why do camels have a leathery tongue?

  So that they are able to chew dessert plants that have thorns, the pants are also a good source of water
• Why do Camels have Long lashes?

  To keep dust out of their eyes
• Why do Camels have wide feet?


  Camels having wide feet prevents them from sinking into the sand
• Why do Camels close the nostrils?


  To keep dust out of their noses
• What are functional adaptations of Camels?

  • They have concentrated urine
  • Dry faeces Both to reduce water loss
• Kangaroo rats

  • live in deserts
  • nocturnal, avoid day time heat
  • live in burrows underground during the day to keep cool and protected from predators
• Arctic Foxadaptation

  Have thick fur that provides insulation and reduces heat loss to the air
• Arctic fox adaptation


  Fur on soles of feet that reduces heat loss to ice and snow
• Arctic Fox adaptation


  Small ears reduce surface are and heat loss
• Arctic Fox adaptation


  White coat helps them to camouflage which helps them to hunt prey
• Cacti adaptations

  • small leaves reduces water loss
  • spine protects them from predators
  • extensive roots catch water after rain fall before evaporation
  • they store water in their stems so they can survive month without rain
• What is an example of an extremophile?

  Deep sea vent
• What is the definition of an extremophile?

  An organism that is adapted to extreme conditions
• What conditions can extremophiles live in?

  • High pressures
  • High temperature
  • High concentration of salt
• predator, prey relationship


  Number of predator and prey rise and fall in cycles, this is only true in a stable community

  
• How can the relationship change?

  There could be a drought or a new predator arrival, both abiotic and biotic factors can affect the relationship
