2
Temperature affects the rate of reactions in living things
This means that higher temperatures cause rapid plant growth in summer and lower temperatures cause hibernation in hedgehogs and frogs in winter
What does temperature affect in living things?
It affects the rate of reactions in living things
What affect does the high temperatures of summer have on organisms?
It causes rapid plant growth
What affect does the low temperatures of winter have on organisms?
It causes hibernation in hedgehogs and frogs
Name two organisms which hibernate
Hedgehogs
Frogs
Write a note on how rainfall affects organisms.

Rainfall provides the water that is essential for life
This means that only plants such as cacti can live in areas of low rainfall (deserts)
Plants in tropical rain forests require high and regular rainfall (along with high temperatures)
What does rainfall provide?
The water that is essential for life
What type of plant lives in areas of low rainfall (deserts)?
Cacti
Where do cacti live?
In areas of low rainfall such as deserts
Give an example of an ecosystem that has low rainfall
