Worked Solution

Step 1: The new predator reduces the population of both primary and secondary consumers. Step [2-9]: Fewer primary consumers (herbivores) mean less grazing on producers. Step [2-9]: Consequently, the producer population will have less predation and will likely increase.

Correct answer: The producer population will eventually increase.
