1. Year 7 White
Adaptations.

2. What does adaptation mean?
A change in structure, function, or behaviour by which a species or individual improves its chance of survival in a specific environment.

3. How does adaptation help organisms?
Well adapted organisms are better at coping with extremes of weather
They are better at competing for food
They are better at escaping from predators
They are more likely to survive in their habitat and produce offspring

4. It is always a struggle for plants and animals to survive
ANIMALS STRUGGLE :
For food
For water
For protection against weather
Against being eaten by predators
Against disease
Against accidents
PLANTS STRUGGLE:
For water
For light
For minerals in the soil
Against weather
Against disease
Against being eaten

5. Task 1: 2 different habitats
Identify the key features of these habitats?

6. A desert habitat Every living organism has been adapted to live in a
particular environment.
A desert can have very little rainfall
There is a lot of sunshine during the day
There is very little shade
The temperatures can get very hot
At night it can become very cold

7. An arctic habitat
This sort of habitat can have extremely low temperatures
The ground is covered with white snow for most of the year

8. Task 2: Adaptation
How are the camel and the polar bear adapted to their environments?

9. Adaptation Example 1: The camel GCSE Science Chapter 1
Stomach can hold 20 litres of water
Produces very little urine
Fat stored in hump
No insulating fat under the skin
Flat feet with large surface area
can drink 20 litres of water in just a few minutes
Two rows of long eyelashes to protect against blowing sand and the sun
Nostrils can be closed to keep out blowing sand
Broad, flat, leathery pads at the bottom of their hooves Function: Pads spread out when the camel places its feet on the ground thus creating a "snowshoe effect" and preventing the camel from sinking into the san

Chapter 1

10. Example 2: The polar bear
Animals like polar bears will have a thick insulating coat
They usually have a large amount of body fat
They have a large body size to surface area ratio (Small ears and compact bodies reduce surface area)
They have a camouflaged coat
Small and rounded ears - Prevents water from entering the bear's ears and freezing their eardrums, u see, big ears, more water

11. Comparing two Foxes
These two foxes are closely related, but because they have adapted to live in very different habitats they look very different
In your workbooks, compare the adaptations of a Fennec Fox and an Arctic Fox to their environments.
GCSE Science
Fennec Fox
Arctic Fox

12. Answer
The Fennec Fox is smaller than the arctic fox, giving it a larger surface area to volume ratio which increases rate of heat loss Its longer ears also increase surface area to volume ratio; it has less fat beneath its skin so heat can be lost more easily.

13. Booklets.
What adaptations does an Elephant have?

14. Elephant Adaptations Large trunk for getting food
Large trunk to suck in water and squirt into mouth
Flap ears to stay cool

15. Cheetah Adaptations Running speed Long thin tail for balance and speed
Pointed pad on paw to help them stop

16. Frill Neck Lizard Adaptations
Camouflage
Changes activity levels in response to temperature and water levels
Frill on neck to scare of predators

17. Hawkfish Adaptations Camouflage Lay their eggs in the coral
Stay around the reef for protection
