Key Area 5 Flashcards
What is dormancy
An organism reduces all processes to survive extreme conditions
What happens during dormancy
An animals metabolic rate, heart rate, breathing rate and body temperature all decrease saving energy
What are the 2 types of dormancy
- Predictive dormancy happens before adverse conditions
- Consequential dormancy happens after adverse conditions
What are examples of dormancy
Hibernating, aestivation, daily torpor, predictive dormancy and consequential dormancy
What is hibernation
A period of inactivity where the metabolic rate, body temperature, heart rate, and breathing rate reduce
What is aestivation
Animals go into a state of deep sleep with a reduced metabolic rate
What is daily torpor
Animals enter dormancy on a 24 hour cycle. Heat, breathing rate and body temperature reduce
What is migration
The regular movement of species members from one place to another
What influences migration
Innate and learned behaviour
What is innate behaviour
Behaviours which are inherited from parents eg direction of travel
What is learned behaviour
Behaviours that’s are gained from experience eg specific places to stop in a journey
