Title: Adaptation To Daily


1
Adaptation To Daily Seasonal Changes
  • D. Crowley, 2008

2
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

15
Adaptations
  • Complete the adaptations worksheet

16
Adaptations
  • Complete the adaptations worksheet

17
Population Change
  • 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
