Well, let's say a hawk eats a mouse. Then he eats another one tomorrow. If you don't have more mice than hawks, you will run out of mice.
The numbers of mice and hawks has to be in equilibrium with the rates that the hawks eat the mice and the speed that the mice reproduce.

Yes, it would have to be. The hawks eat the mice, correct. How many mice does a single hawk eat in a year? Hundreds at least. That means that there would have to be hundreds of mice for each hawk to eat in a year. If there were more hawks than mice, then the number of mice would be decimated and then the hawks would starve. There has to be more mice than hawks.

because a hawk will devour a dissimilar volume of mice. If there are an same volume of mice as there is hawks then each and each of the mice might want to get eaten and then the hawks might want to starve.

Well, if there is only 10 mice and 10 hawks, each hawk has one meal. Then what? Mice would become extinct & hawks would relocate, change eating habits or possible die from starvation... like other animals that have experienced changes in their food change.

Because in a pyramid they are near the bottom so there are more as they can reproduce to replace the numbers eaten by hawks.

because a hawk would have to eat lots of mice to get the energy it needs and so there need to be more mice than hawks.

Anytime a species(mice) is the hunted they produce more offspring to keep the species alive. The less an animal is hunted the fewer offspring they produce.

One hawk can eat more than one mouse.
