The effect of size and shape of a warm blooded animal on how quickly it losses heat.

I recently found out, as the size increases the volume increases. Thelarger the surface area/volume ratio the larger the heat loss. This isbecause the molecules have less distance to travel and more s ... eat faster than larger one's. Thereis also a relationship between the shape and surface area/volume ratio.Evidence of this can be found in nature as Bergmanns rule suggests. Polarbears are the largest ...

Physical effects of scaling on organisms

of a sphere is (4π/3)r3 and the surface area of a sphere is (4π)r2. So the surface to volume ratio is 3/r. As the animal becomes larger, the surface to volume ratio decreases. Therefore we woul ... ey require a greater area for food and oxygen intake to compensate for the increased volume to area ratio. For example, if an animal absorbs nutrients through the external body wall, and we scaled up ...
