You will determine the relationship between surface area and volume through the manipulation of cubes and learn the importance of this ratio in organisms.
After completing this tutorial, you will be able to complete the following:
Surface area-to-volume ratio, which is the amount of surface area per unit of volume, is a major concept in Biology. An organism's surface area-to-volume ratio impacts everything from its exposure to the environment, to how well it diffuses substances, to the regulation of its body temperature.
Large animals have a smaller surface area-to-volume ratio than small animals. This lower ratio means that they do not lose heat as quickly as a smaller animal would in a similar habitat. For this reason, there are many examples of animal adaptations that impact an animal's surface area-to-volume ratio, thus affecting heat loss from the animal. Some examples include the large ears of African elephants as compared to Asian elephants, the large ears of many desert animals, or the relatively large bodies but short appendages of artic animals.
