Answer:
The answer is C, 40,000.
Explanation:
You can obviously tell that 400 is too low... that's one meal for all of the turtles! They would need 40,000 minnows because it's a stable number. They can reproduce, and keep the population up. 4,000, though, is too low because they wouldn't have enough time to reproduce and continue to keep the population alive. Therefore, 40,000 should be a stable population.
