Aportion of grass in a prairie ecosystem was destroyed by wildfire. what will most likely happen to the population of bison that feed on the grass

A limiting factor is the factor which negatively affects the growth, abundance and distribution of a species in an ecosystem. Example of limiting factor resource  (food, shelter), predator, natural disasters and other factors. A grass being a limiting factor after the wildfire for the growth of bison population in the prairie ecosystem will likely to cause decrease, extinction and migration of the bison from the prairie ecosystem. As, grass is the chief vegetation in the prairie ecosystem and population of bison is largely dependent on the grass.

what is the question because that is not a question.
