Answer:
the population of mice would decrease
Step-by-step explanation:
In a food chain, one organism is being eaten by others. In every food chain, there are producers and different level of consumers. In the given food chain of the prairie ecosystem, plant producing seeds are the producers and mice are the primary consumers and foxes which feed on mice are the secondary consumers. If the fox population suddenly increased: the population of mice will decrease due to more demand for food from mice by the increased population of the fox.
