1
Q

What are adverse conditions?

A

The cold/lack of food in winter and drought and extreme heat of summer create conditions which are beyond the tolerable limits of an animals normal metabolic rate

Q

What is dormancy ?

A

Where is the development of an organism is temporarily suspended minimising metabolic activity and therefore saving energy until the environmental conditions can improve

Q

What is daily torper (predictive)?

A

Sleep, Occurs every day for part of the day

Involves a reduction in breathing rate, heart rate , metabolic rate and temperature

allows endotherms with high metabolic rate to save energy during a time where they would be unable to find food

Q

Hibernation (productive consequential)

A

Used to escape cold weather and lack of food supplies during winter

Before hibernation the endotherms consume extra food which is laid down as fat store which can be used during hibernation

During hibernation body functions change dramatically, there is a lower metabolic rate, breathing rate, heart rate, and a temperature so minimal energy is expended

Q
