    I got it to be the other way around:
    1- whale
    2- tiger
    3- bacterium

    This is because as organisms get larger their surface area to volume ratio gets smaller as the proportion between them decreases. I.e a bacterium has lots of surface and not much insides, whereas a whale has a bit of surface but a lot more insides. The ratio is SA/volume so if the volume is bigger, you are dividing by a larger number and so the end ratio is a smaller number.
    Hope that helps

    well in terms of size yes, but in terms of surface to volume ratio it would be the opposite. Have a look at this and see if you understand
