If a portion of the grass was destroyed by wildfire, then the population of bison that feed on the grass will decrease. This is because there would be very little grass left for them to eat, and they don't eat anything else.
Answer:
The black and yellow bird population would begin to starve and would be forced to find alternative food, or die off. This would then send ripples through the food web, causing almost every species to be effected by the grasshoppers being gone.

It would decrease as their prime food source would be taken away. This would result in a decline in population as the birds wouldn’t have sufficient food.
Hope that helps. :)
