  1. ADAPTATIONS

  2. Adaptations • Every organism has features that allow it to survive in its own particular habitat • These features are called adaptations.

  3. The white-faced heron • Lives in the wetland areas throughout NZ • Can you think of any adaptations it may have to live here?

  4. The white-faced heron • Lives in the wetland areas throughout NZ • Long legs to walk through swampy areas to find food • Long, pointed beak so it can collect snails, insects, frogs and fish from the water and mud • Large, strong wings to help it escape from danger • These adaptations make it successful in its habitat

  5. Types of adaptations • Structural adaptations – the shape and size of the organism (e.g. beak shape, skeleton, etc.) • Functional adaptations – the workings of an organism’s body (e.g. digestion, photosynthesis) • Behavioural adaptations – how the organism behaves (e.g. Predator avoidance, how they find food, mates, etc.)

  6. The morepork

  7. Leopard seal skull

  8. Bird beaks

  9. Structural, behavioural, functional? • You only have one arm • Every time you hear your name, you put both your hands up for protection • You have a hunched back for protection • You need to pull your jersey over your head because you don’t like the light • Your knees and elbows don’t bend • You can’t speak

  10. Structural, behavioural, functional? • You walk sideways • Your thumbs don’t work on either hand • Your voice is high pitched so that predators can’t hear you • When you hear the word “don’t” you whistle • You drop to your hands and knees if a male speaks to you

  11. Poster! • Create your own habitat and an organism within it that has structural, behavioural and functional adaptations to suit where it lives. • Work individually – homework if you don’t finish in class, will collect tomorrow for marking

  12. Active at night (nocturnal) to avoid predators – behavioural Exemplar – Kiwi Habitat: NZ native bush Short, compact body for easy movement through dense bush - structural Fluffy feathers for warmth – structural Nose helps kiwi to smell in soil for food – functional Nose at end of beak – structural Strong feet for digging and moving rapidly through bush – structural Long beak for reaching deep into leaf litter and soil to find food – structural
