Final answer:
Campers likely fed the normalized bunnies with suitable food like vegetables or fruits collected from their surroundings, which they spent two to three hours a day gathering.
Step-by-step explanation:
The question 'What did the campers feed the normalized bunnies?' suggests that the campers may have been providing food to wild bunnies which had become accustomed to human presence. While the provided reference text doesn't specifically mention bunnies, it discusses how food was collected for approximately two to three hours a day and shared back at the campsite.
Also, an observation is made within a forest where bird chicks are noticed to be hungry. Considering these points, a reasonable assumption could be that the campers fed the bunnies any suitable food they collected, such as vegetables or fruits found in their environment, which would be safe and appropriate for the bunnies to eat.
