Heat Loss Flashcards
1
Q
What shape has the smallest SA:VOL ratio?
A
A sphere.
2
Q
What shape has the greastest SA:VOL ratio?
A
Long and thin shapes.
3
Q
Describe heat loss in terms of an organism with a high SA:VOL ratio.
A
Organisms with a high SA:VOL ratio will lose a greater proportion of their heat at a faster rate than an organism with a smaller SA:VOL ratio.
4
Q
Describe metabolism in terms of an organism with a high SA:VOL ratio.
A
The smaller the object the greater the SA:VOL ratio therefore the greater the heat loss to the environment and the greater metabolism required to maintain homeostasis.
