* Metabolic Rate: Mice have a much higher metabolic rate than elephants. This means they burn calories much faster and need to eat more frequently to maintain their energy levels.
* Body Size: Elephants are significantly larger than mice. Their larger size means they have a lower surface area to volume ratio, which helps them retain heat and conserve energy.
* Digestion: Mice have a relatively short digestive system, meaning they don't absorb all the nutrients from their food as efficiently as elephants. Therefore, they need to eat more frequently to compensate for the lost nutrients.
* Energy Needs: Mice have a higher energy demand due to their high activity level and smaller body size. They need to constantly search for food and expend energy for survival. Elephants, on the other hand, are less active and have a larger body mass, requiring less energy per unit of body weight.
In summary, the higher metabolic rate, smaller body size, less efficient digestion, and higher energy demands of mice necessitate more frequent eating compared to elephants.
