2. Some plants developed thorns to stop animals eating them
  1. Some organisms develop poisins/warning colours to deter prey
Extremophiles
1. Organisms adapted to live in areas with a high salt concentration/high pressure and temperature
Animal Adaptation
1. Changes to surface area
2. Thickness of insulating coat
3. Amount of body fat
