- Adaptations
- Desert Animals
- Large surface area to volume ratio
- They lose more body heat keeping them cool
- Produce small amounts of concentrated urine
- Lose less water
- Sweat very little
- Camels do this by tolerating big changes in body temperature
- Kangaroo rats do this by living in burrows where it's cool
- Large surface area to volume ratio
- Arctic Animals
- Small surface area to volume ratio
- Less body in contact with cold air so less heat is lost
- Thick layer of blubber (fat)
- Acts as an insulator to reduce heat loss
- Acts as an energy source when there is little food
- Thick hairy coats
- Acts as an insulator keeping heat in
- Greasy fur sheds water
- This reduces cooling due to evaporation
- Camoflage
- Most arctic animals have white fur to blend in with the ice to sneak up on prey
- Polar Bears and arctic foxes have white fur
- Small surface area to volume ratio
- Desert Plants
- Small surface area to volume ratio
- Reduces water loss
- Have spines instead of leaves
- Plants lose water vapour through leaves so by not having leaves they reduce water loss
- Water storage tissues
- Cacti stores water in their thick stems
- Roots
- Some have shallow but extensive roots to absorb water quickly
- Some have deep roots to access underground water
- Small surface area to volume ratio
- Deterring Predators
- Armour
- Thorns
- Sharp spines
- Shells
- Poisons
- Bees
- Poison Ivy
- Warning colours
- Scare off predators
- Wasps are black and yellow
- Armour
- Microorganisms
- Extremophiles
- Adapted to live in extreme conditions
- Volcanic vents
- Very salty lakes
- High pressure on the sea bed
- Adapted to live in extreme conditions
- Extremophiles
- Desert Animals
