Final answer:
Adding an enzyme to break down dead organisms and supply the population with additional nutrients after reaching carrying capacity will cause the graphed line representing population growth to increase again.
Step-by-step explanation:
When an enzyme is added to break down dead organisms and supply the population with additional nutrients after reaching carrying capacity, the graphed line representing population growth will begin to increase again because the population is no longer limited by a lack of nutrients. With the availability of additional nutrients, the population can continue to grow.
