Different sized birds have different surface area to volume ratios.
The table shows the surface areas and volumes of four different groups of birds:
| Bird genus | Surface area (m2\text{m}^2m2) | Volume (m3\text{m}^3m3) |
|---|---|---|
| Cygnus | 1.40 | 0.10 |
| Passer | 4.5 × 10-3 | 1.5 × 10-4 |
| Struthio | 4.80 | 0.80 |
| Columba | 0.12 | 5.0 × 10-3 |
Which of the options, A to D, is the correct order of surface area to volume ratios for the different birds, arranged from the largest to the smallest?
Passer, Cygnus, Columba, Struthio
Columba, Passer, Cygnus, Struthio
Passer, Columba, Cygnus, Struthio
Struthio, Cygnus, Columba, Passer
