Very small animals are rarely found in polar region because
1 Small animals have a larger surface area relative to their volume, so they lose body heat very fast when it is cold outside
2 Small animals have a smaller surface area relative to their volume, so they lose body heat very fast when it is cold outside
3 Small animals have a larger surface area relative to their volume, so they gain body heat very fast when it is cold outside
4 None of the above
Explanation:
Very small animals are rarely found in polar region because small animals have a larger surface area relative to their volume, so they lose body heat very fast when it is cold outside.
