Habitats, resources and adaptation
Explain how a feature can help in a particular environment.
Understand the idea
Connect feature and function
Explain how a feature can help in a particular environment.
Resources can be limited
Organisms need suitable conditions as well as food and water.
Avoid intention stories
An inherited feature is not acquired simply because an individual wants it.
Worked examples
Which description best matches a habitat?

Try it yourself
Why might a rock crevice be useful to a small animal in a hot, dry place?
A pond's water level falls sharply. Which effect is plausible?
- Available aquatic habitat may decrease.
- The pond becomes a mountain.
- Every species must increase.
- No organism can be affected.
Which example describes camouflage?
- A fish swims quickly.
- A plant grows roots.
- A moth's colour resembles the bark it rests on.

Explain why the same feature may help in one habitat but not another.
Answers and marking notes
Answers and marking notes
- It can offer shade, shelter and a cooler or less exposed location.
Accept a plausible link to conditions, not a claim that all crevices are suitable.
- Available aquatic habitat may decrease.
Less water can reduce usable habitat.
- A moth's colour resembles the bark it rests on.
Similarity to the background can make an organism harder to notice.
- Conditions differ; a feature useful for one temperature, surface or food source may be less useful elsewhere.
Require a clear feature–environment connection.
