Daily Changes
Daily ChangesAdaptations
How are plants and animals adapted for daily changes?
• Some plants open their flowers during the day to attract insects for
pollination and close them by night for protection e.g. daisies
• Some animals are nocturnal and only come out by night to avoid
predators e.g. dormice. However, other animals are nocturnal so
they can catch nocturnal prey, e.g. owls.
• Some animals adapt to the tide and feed when the tide is in and
close up when the tide goes out to prevent them drying out e.g. sea
anemones.
Seasonal Changes
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 tem
• Deciduous leaves lose their leaves (in case of permafrost)
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
Flowers That Open at Night
If a flower is native to an area where the creatures it lives among are
largely nocturnal, that’s the time when it’s most likely to be pollinated.
Animals like bats, insects and moths come out at night to move
around the night garden, and as they do, they collect pollen from one
flower and transport it to another, ensuring a new generation of the
species. Many desert flowers are night-blooming, since the evening
hours are the most temperate and the most likely to draw out the
wildlife that pollinates the flowers.
Moonflower (Ipomea Family)
Once the sun goes down, these big,
white flowers spring open their petals.
