Final answer:
A larger dinosaur had relatively less surface area compared to its volume than a small dinosaur due to the specific relationship between surface area and volume that exists as objects increase in size.
Step-by-step explanation:
Because of the surface-area-to-volume relationship, a larger dinosaur had relatively less surface area than a small dinosaur. This concept is related to the idea that small cells or objects have a greater surface area per unit volume which allows for more interaction with the environment. This is crucial for biological processes such as nutrient uptake and waste expulsion.
For a larger object or organism, the surface area does not increase at the same rate as the volume does as they grow larger, leading to a decrease in the surface area-to-volume ratio. This ratio becomes important in understanding why larger dinosaurs might have faced challenges in maintaining efficient physiological processes.
