adaptations

• physical adaptations in camels

  humps on the back store fat - thermal insulator, by storing in one place it allows heat loss from other parts of body - this reduces waterloss from sweating - metalolic reaction can be used to produce water from fat

  thick coat - insulates the top of the camel from the heat of the sun which reduces water loss

  inside of mouth is leathery - can chew desert plants which often have thorns , these plants can be a good source of water

  long eyelashes to keep dust out of eyes and can also close nostrils to keep dust out

  wide feet to prevent sinking into sand
• what are functional adaptations

  adaptations to the body functions of an organism
• functional adaptations of camel

  produce concentrated urine and dry faeces to reduce water loss

  can tolerate very large changes in their body temperature which helps with intense heat
• what are behavioral adaptations ?

  adaptations to an animals lifestyle or behavior
• behavioral adaptations in kangaroo rat

  lives in desert

  nocturnal so avoid heat of daytime

  live in burrows underground so keep cool and are protected from preditors
• arctic fox physical adaptations

  thick fur - insulation and reduce heat loss

  fur on soals of feet - reduce heat loss to ice

  small ears - reduce surface area to reduce heat loss

  white coat - camoflague - helps hunt pray
• plant adaptations cacti

  adapted to dry conditions

  small leaves to reduce water loss or no leaves only spines ( spines protect from animals too )

  shallow and extensive roots - catch as much water as possible and can store water in stem so can survive many months without rain
• extremophiles

  live in harsh conditions

  adapt to high temperatures, pressures and salt concentrations
