Smaller Organisms Can Cool Down Quicker Flashcards
1
Q
What do smaller organisms have?
A
Bigger surface area to volume ratios
2
Q
What can organisms with a bigger surface area to volume ratio do?
A
They can gain/lose heat faster because there is more area for the heat to transfer across
3
Q
How does this help smaller organisms in hot climates?
A
Lose body heat more easily in hot climates and reduces the chance of them overheating
4
Q
What does this mean for smaller organisms in cold environments?
A
There very vulnerable
5
Q
What can organisms with a smaller surface area to volume ratio do?
A
Gain/lose heat more slowly because there is less area for the heat to transfer across
6
Q
Why do animals living in cold conditions have a compact shape?
A
To keep their surface area to a minimum, reducing heat loss
