A wildlife biologist studied the same rabbit population in two fenced fields for 5 months. Both fields started with 30 rabbits. The fields were the same size and had the same weather. The only difference was the amount of grass available (a resource). Data:
  • Field 1 (less grass) → 28 rabbits after 5 months
  • Field 2 (more grass) → 55 rabbits after 5 months
Which claim about population size is incorrect based on the evidence? (Resources can limit population size.)
