QUESTIONS WITH COMPLETE
SOLUTIONS
Are bees endothermic or ectothermic? Why? - Answer- are ectothermic and this refers
to organisms that control body temperature through external means, insects small in
size
Endothermic means? - Answer- where heat is primarily generated as a
result of internal metabolic
processes
Homeothermic means? - Answer- Where the insects maintain a constant temperature
Ectotherms can also be what? - Answer- Homeotherms
If the temperature is 100 degrees and drops to 50 degrees, how fast will its internal
temp decline? - Answer- Drops by almost 50%
How do bumble bees warm up in the morning? - Answer- Shivering
How do honey bees warm up? - Answer- beating their wings inside the hive during the
coldest of days generating heat
How do butterflies sit when cool? - Answer- Perpindicular to sun

• Oxygen consumption • Heart rate
• Breathing
The prolonged and deep torpor during winter months is known as - Answer- Hibernation
The prolonged and deep torpor during summer months is known as - Answer-
Aestivation
