Final answer:
If the population of toads immediately increases, it will likely cause a decrease in the population of hognose snakes.
Step-by-step explanation:
The population of hognose snakes will likely decrease if the population of toads immediately increases. This is because hognose snakes are predators that feed on toads. If there is a sudden increase in the number of toads, it would provide more prey for the hognose snakes, causing their population to grow. However, if the population of toads continues to increase, the availability of prey may become limited, leading to a decline in the hognose snake population.
