Adaptation To Daily & Seasonal Changes
To know how organisms can adapt to suit daily and seasonal changes

3. Animal Adaptation
Complete the animal adaptation worksheet – cut out the animal and write down how it is adapted to its environment

4. Animal Adaptation
Elephant (dry grassland) – trunk to suck up water to drink and cool itself down; tusks for protection / mating / knocking over trees to eat; large ears to help it cool down; little hair so as to not overheat; large size aiding protection; large feet to support body

5. Animal Adaptation
Dolphin (sea) – fins to swim; streamlined; air hole on top of head allowing it to breathe

6. Animal Adaptation
Frog (pond) – long tongue to catch flies; camouflage; strong hind legs for leaping

7. Animal Adaptation
Polar bear (Arctic) – white fur for camouflage; thick hair to keep warm; sharp claws for catching prey & gripping ice; large feet to stop it sinking into the snow

8. Animal Adaptation
Zebra (grassland) – tall to spot predation; stripes for camouflage; strong legs for running quickly

9. Daily Changes Many habitats do not stay the same all the time
Daily changes to the environment include: -
Changes in the amount of light (between day and night)
Changes in the temperature
Changes in the amount of water (i.e. rainfall / tidal variations)

10. Seasonal Changes Many habitats do not stay the same all the time
Seasonal changes to the environment include: -
Changes in temperature between the seasons (warm in summer, cold in winter)
Changes in the amount of light (between long daylight hours in the summer to shorter days in the winter)
Changes in vegetation due to conditions (lots of vegetation in summer, to bare trees and snow-covered grown in winter)

11. Daily Changes - Adaptations
How are plants and animals adapted for daily changes?
Most flowers open their petals during the day (for pollination), but close them at night for protection
Some animals avoid predation by being nocturnal (come out at night) – however some predators specialise at hunting during the night!
Factors such as the tide (in or out) also affect the distribution of organisms

12. Seasonal Changes - Adaptations
How are plants and animals adapted for seasonal changes?
Some organisms hibernate during the cold winter months when food is scarce
Different sized coats are grown by animals, e.g. a summer and winter coat
Insects spend the winter as pupae
Animals store food during plentiful times in preparation for when food becomes scarce
Some organisms migrate
Flowers die off in winter as there are fewer birds or insects to pollinate them
Deciduous trees lose their leaves (in case of permafrost)

13. Blue Planet Watch the deep episode of The Blue Planet
How are these organisms adapted to their environment?!

14. Hibernation What is hibernation? How does this help some organisms?
Hibernation occurs in some organisms, whereby they slow their body functions (e.g. breathing; metabolism; heart rate)
This saves the organism a great deal of energy (but they must store a great amount of energy during the summer when food is plentiful)
E.g. bats; tortoises; hedgehogs
*Bears are not true hibernators, they only slow down (slow heart rate) but their body temperature remains the same

Complete the population change worksheet

18. Population Change
Producers – green plants; primary consumers – mice; secondary consumers - owls
Number of mice depends on amount of food (i.e. producers)
Number of owls linked to amount of mice – as season changes availably of food varies, allowing for either more individuals (summer) or fewer individuals (winter)
As mouse numbers increases, more owls can predate them, in turn reducing the mouse number leading to a decline in owl population size
