19. How could humans alter carrying capacity so the bullfrog population returns to its normal level? a. Humans could alter the carrying capacity by breeding bullfrogs b. Humans could alter the carrying capacity by hunting the snakes c. Humans could alter the carrying capadty by hunting the bulifrogs d. None of the above will help alter the carrying capacity 20. What is another possible solution to this problem? Explain why it will help after the carrying capacity of the bulifrog population?

## Step 1<br />The carrying capacity of a species refers to the maximum number of individuals of that species that an environment can sustain indefinitely. This is determined by the availability of resources such as food, water, and shelter, as well as the presence of predators and diseases.<br /><br />## Step 2<br />In the given problem, the carrying capacity of the bullfrog population is being altered by the presence of snakes, which are predators of bullfrogs. This is causing the bullfrog population to decrease.<br /><br />## Step 3<br />To restore the carrying capacity of the bullfrog population, humans could alter the carrying capacity by reducing the number of predators, in this case, snakes. This would allow the bullfrog population to increase and return to its normal level.<br /><br />## Step 4<br />Another possible solution to this problem could be to introduce a natural predator of the snake species. This would help control the snake population and indirectly allow the bullfrog population to increase.
