Why were there 50 wolves? It was in V31 and i really want to know the answer

I guess it's something along the lines of "going up the food chain, the number of organisms in the trophic levels decreases". Then you have to explain why this is so. I wrote wolves rely on moose for their source of food, some moose die from disease or lack of nutrition. So the remaining moose keep the species going, otherwise a disturbance in the food chain would arise.

They asked why the wolves population didn't increase, when the population of the moose was huge right?
