Adaptations of Living Things: Year 5 Study Guide
Plants and animals have features and behaviours that help them survive in their habitats.
An adaptation is a feature or behaviour that helps a living thing survive and reproduce in its environment. Structural adaptations are body parts: a kangaroo's strong back legs, a koala's thumbs and a fish's gills. Behavioural adaptations are actions: birds migrating, echidnas curling into a ball or a possum being active at night.
Australia's long isolation produced many unique species, from monotremes (the platypus and echidna) to marsupials (kangaroos, wombats) and plants such as eucalypts, which survive fire and drought.
Examples of adaptations
| Living thing | Adaptation | How it helps |
|---|---|---|
| Camel (introduced) | wide feet, stores fat | walks on sand, survives with little food |
| Red kangaroo | powerful legs, hops | travels far for food and water |
| Mulga tree | deep roots, small leaves | finds water, loses less water |
| Platypus | webbed feet, sensitive bill | swims and finds prey |
| Banksia | seed cones open after fire | new plants grow after bushfire |
Why adaptations matter
A habitat provides food, water, shelter and space. Animals suited to the habitat survive better. Over very long periods, helpful features become more common in a population. When habitats change, species that cannot adapt may become endangered. Introduced species such as foxes, cats and rabbits harm native animals that did not develop defences against them.
For example, desert.
Heat, little water.
Burrows, night activity.
Loses less water.
Protecting Australian wildlife
Threats include habitat clearing, bushfires, climate change and feral predators. Protecting habitats, building wildlife crossings, controlling feral animals and breeding programs help. First Nations Peoples have deep knowledge of local plants and animals and traditional practices such as seasonal calendars, which modern land managers are learning from.
Worked example and common misconceptions
Example: The thorny devil collects dew on its skin and channels it to its mouth, which is a structural adaptation for the desert. Common misconceptions: thinking individuals change on purpose to adapt (adaptations build up over generations) and thinking all adaptations are physical. Look for both body features and behaviours.
Check your understanding: model answers
1. For example, a koala's strong claws (structural) and a possum being active at night (behavioural). 2. New plants can grow when the ground is cleared. 3. For example, feral cats or land clearing.
✨ Key Takeaways
- Adaptations help survival.
- They can be structural or behavioural.
- Habitats provide the needs of living things.
- Introduced species can harm native wildlife.
