Answer 2

Answer: b. The number of bison will decrease.

Explanation:

A food chain can be define as a linear sequence of transfer of food and energy when one organism consumes the other. In the given situation the bison population is mainly dependent on grass for their food requirements. But with the loss of a portion of grass by a wildfire the food chain of the prairie ecosystem will be negatively affected. This will likely to limit the population of bison as they will experience the scarcity of food.
