ADAPTATIONS

Adaptations

• Every organism has features that allow it to survive in its own particular habitat

• These features are called adaptations .

The white-faced heron

• Lives in the wetland areas throughout NZ

• Can you think of any adaptations it may have to live here?

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

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.)

Bird beaks

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

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

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
