Daily Changes

Daily Changes-Adaptations

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.
