Q

Structural adaptations

A
  • camel hump on back
    = stores fat
    = thermal insulator in one area
    = heat loss from other areas of body
    = reduce water loss by sweating
  • camels have thick coat
    = insulate top of camel from heat of sun
    = reduce sweating
  • camels have wide feet
    = prevent sinking into the sand
  • arctic fox has fur on soles of feet
    = reduces heat loss of snow and ice
    • arctic fox has small ears
      = reduce surface area
      = reduce heat loss
  • cacti have small leaves or no leaves
    = reduces water loss
  • cacti have spines
    = protection against other animals
