What this dot point is asking

This dot point wants you to describe the characteristics that all living things share, explain what a habitat is and what it provides, and explain how plants and animals are adapted to survive where they live. The big idea is that living things are different from non-living things because they do certain things, such as grow and reproduce, and that each living thing has features that suit it to its particular home, or habitat.

The answer

The characteristics of living things

All living things, whether a plant, an animal or a tiny germ, share certain characteristics that non-living things do not have. The main ones are:

They grow: they get bigger and develop over time.
They need energy: animals get it from food, and green plants make their own food.
They get rid of waste: they remove the waste their bodies make.
They respond to their surroundings: for example, a plant grows toward light, and an animal moves away from danger.
They reproduce: they make young (more of their own kind).
They move: animals move around, and even plants move slowly, such as turning toward light.

A car can move and use fuel, but it is not alive because it cannot grow or reproduce by itself, which shows why we need the full list of characteristics.

What a habitat is

A habitat is the place where a living thing lives. A pond, a forest, a desert and a garden are all habitats. A habitat provides the things a living thing needs to survive, such as:

Food (or the conditions a plant needs to make food).
Water.
Shelter and a safe place to live.
The right conditions, such as a suitable temperature.

Different habitats provide different conditions, which is why different living things are found in different places.

What an adaptation is

An adaptation is a feature of a living thing that helps it survive in its habitat. Over a very long time, living things have developed features that suit them to where they live. An animal or plant that is well adapted to its habitat is more likely to survive there.

Adaptations in animals

Animals have many adaptations suited to their habitat:

A camel in the hot desert can go a long time without water, stores fat in its hump, and has wide feet to walk on sand without sinking.
A polar bear in the freezing Arctic has thick fur and a layer of fat to keep warm, and white fur to blend in with the snow.
A fish is adapted to live in water, with a streamlined shape to swim and gills to take oxygen from the water.

Adaptations in plants

Plants are adapted too:

A cactus in the dry desert has a thick stem to store water, and spines instead of leaves to lose less water.
A water lily has broad floating leaves to catch plenty of light on the surface of a pond.

Because each living thing is suited to its own habitat, it may not survive in a very different one, where the temperature, water or food are not right for it.

Worked example: explaining why a polar bear suits the Arctic

A polar bear lives in the freezing, snowy Arctic. Explain step by step how its adaptations help it survive there, and why it would struggle in a hot desert.

Step 1: Identify the conditions of the habitat

The Arctic habitat is extremely cold and covered in white snow and ice. To survive, an animal must be able to keep warm and find food in this harsh place.

Step 2: Match the keeping-warm adaptations

The polar bear has thick fur and a thick layer of fat under its skin. These trap heat and keep the bear warm in the freezing cold. This adaptation directly suits the cold conditions.

Step 3: Match the other adaptations

The polar bear has white fur, which blends in with the snow. This helps it creep up on the seals it hunts without being seen, so it can catch food in its habitat.

Step 4: Explain why it would struggle elsewhere

In a hot desert, the same thick fur and fat would make the polar bear far too hot, and its white coat would stand out instead of hiding it. Its adaptations suit the cold Arctic, not a hot desert, so it would not survive there. This shows that adaptations suit a living thing to its own particular habitat.

Examples in context

Example 1. Fish in a tank. A pet fish shows both ideas at once. Its habitat is the water in the tank, which provides oxygen (dissolved in the water), food and the right temperature. The fish is adapted to this watery home with gills to take in oxygen from the water and fins to swim. Take it out of water and it cannot survive, because it is adapted to live in water.

Example 2. A cactus on a sunny windowsill. A cactus comes from a hot, dry desert, so it is adapted to survive with very little water: it stores water in its thick stem and has spines instead of leaves to lose less water. This is why a cactus needs only a little watering at home, while a leafy houseplant from a wetter habitat needs much more.

Try this

Cue. State two characteristics that show something is a living thing. Any two of: it grows, needs energy (food), gets rid of waste, responds to its surroundings, reproduces, or moves.
Cue. State what is meant by a habitat and give one example. A habitat is the place where a living thing lives, for example a pond, a forest or a desert.
Cue. Give one adaptation of a camel and explain how it helps it survive in the desert. For example, the camel stores fat in its hump (or can go a long time without water), which helps it survive where food and water are scarce.

Exam-style practice questions

Practice questions written in the style of SEAB exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.

Original4 marksLiving things share certain characteristics. (a) State two characteristics that all living things have. (b) A car can move and uses fuel for energy, but it is not alive. State one characteristic of living things that a car does not have. (c) Name the place where a living thing lives.

Show worked answer →

(a) Any two characteristics of living things, for example: they grow, they need food (or make food) for energy, they get rid of waste, they respond to their surroundings, and they reproduce (make young).

(b) Any characteristic a car lacks, for example: a car cannot grow, cannot reproduce (make more cars by itself), and does not get rid of waste in the way living things do.

What markers reward: two genuine characteristics of living things, a characteristic a car clearly lacks (grow or reproduce), and naming the habitat as where something lives.

Original4 marksA camel lives in a hot, dry desert and a polar bear lives in the freezing Arctic. (a) State what is meant by an 'adaptation'. (b) Give one adaptation of the camel that helps it survive in the desert. (c) Give one adaptation of the polar bear that helps it survive in the cold. (d) Explain why an animal adapted to one habitat may not survive in another.

Show worked answer →

(a) An adaptation is a feature of a living thing that helps it survive in its habitat.

(b) Any correct camel adaptation, for example: it can go a long time without water, it stores fat in its hump, or it has wide feet to walk on sand without sinking.

(c) Any correct polar bear adaptation, for example: it has thick fur and a layer of fat to keep warm, and white fur to blend in with the snow.

(d) An animal is suited to its own habitat. In a different habitat the conditions (such as temperature or food) are different, so its adaptations may not help and it may be too hot or too cold, or unable to find food, and so may not survive.

What markers reward: a clear meaning of adaptation, one real adaptation each for the camel and the polar bear, and explaining that different habitats have different conditions so the adaptations may not suit them.
