If the population of bar jacks increases, the population of sergeant majors will likely **decrease**, and the population of Caribbean reef sharks will likely **increase**.

This is because an increase in bar jacks, which are predators, can result in a decrease in their prey, such as sergeant majors. As the population of sergeant majors decreases, it may create a more favorable environment for predators like Caribbean reef sharks, leading to an increase in their population as they can find more food.
