1
Q

What is V formation flight in migrating birds?

A

Birds behind the leading bird pick up lift, which costs them less to flap their wings

2
Q

What is hypometabolic?

A

They reduce their metabolic rate prior to migration

3
Q

What is the thermal neutral range?

A

The temperature range in which the animal doesn’t need to metabolically thermoregulate

4
Q

What is endothermy?

A

Generation and regulation of body temperature

5
Q

What is homeothermy?

A

Thermoregulation that maintains a stable internal body temperature regardless of external influence

6
Q

What is ectothermy?

A

Regulation of body temperature through the external environment

7
Q

What is poikilothermy?

A

Internal temperature varies considerably due to the environment

8
Q

What are the three factors affecting heat transfer?

A

Surface area
Temperature difference
Specific heat of conductance

9
Q

How can ectotherms regulate body temperature?

A

Morphology
Behaviour
Physiology
