Adaptations

Cards (7)

  • An adaptation is a feature that enhances the survival and long-term reproductive success of an organism
  • Adaptations help organisms cope with environmental stresses - selection pressures:
    • Find food and water
    • Defend itself from predators
    • Survive physical conditions - temperature changes
    • Respond to environmental changes
    • Reproduce successfully
  • We can separate adaptations three different categories; Behavioural, Anatomical, Physiological
  • Behavioural adaptations can be a combination of both innate - inherited though genes ( spiders building webs) and learned behaviour - observing other animals ( using tools)
  • Behavioural adaptations examples
    • Survival (Possums playing dead and Earthworm contracting)
    • Courtship ( scorpions dancing)
    • Seasonal (migration, hibernation)
    • Anatomical Adaptation Examples: 

    • Body covering (feathers, hair, scales, etc)
    • Colour (camouflage)
    • Teeth (for the diet)
    • Mimicry (copying another animal’s appearance to warn of predators)
  • Physiological (processes that take place inside an organism) adaptation examples:
    • Hibernation
    • Antibiotic production
    • Venom production
    • Cacti store water
    • Changing metabolic reactions
