| Heat loss or heat gain is a function of surface area. Since small animals have a A relative to their volume, they tend to lose body heat very fast, when it is cold outside; then they have to expend B to generate body heat through metabolism. This is the main reason why very small animals are C found in polar regionsChoose the correct options for A, B and C |
| a) | A-larger surface area, B-much larger, C-rarely | b) | A-larger surface area, B-low energy, C-rarely |
| c) | A-smaller, B-less energy, C-rarely | d) | A-smaller, B-much energy, C-rarely |
| (a)A-Larger surface area, B-Much larger, C-Rarely |
