Adaptations

• adaptations = physical features of an organism that makes it more likely to survive in its environment
• smallest in size -> largest surface area to volume ratio
• medium sized -> medium surface area to volume ratio
• largest in size -> smallest surface area to volume ratio
• adaptations: (label hot/cold too, sa to v ratio )

  A) cold

  B) hot

  C) smallest in size largest sa to v ratio

  D) medium sized medium sa to v ratio

  E) largest in size smallest sa to v ratio

  
• large ears -> increase surface area + increase heat loss -> useful for a very warm environment
• large sa to v = increases heat loss
• coat colour -> similar to environment to provide camouflage
• fur -> reduces heat loss
• large body mass -> creates small sa to vol ratio -> reduces heat loss
• morphological adaptations:

  • large ears
  • coat colour
  • fur
  • Large body mass
• Behavioural adaptations = organisms changing their behaviour to increase their chance of survival
• Behavioural adaptations:

  • being nocturnal (to avoid predator)
  • dancing to attract a mate
  • hunting as a pack (to increase chance of survival)
• population size = how many of one type of plant or animal (species) there is in a given ecosystem
