A scientist raised the same species of beetle in three containers for 4 weeks. The only difference was the amount of food provided each week. Data: Container 1 (low food): 18 beetles after 4 weeks; Container 2 (medium food): 44 beetles after 4 weeks; Container 3 (high food): 79 beetles after 4 weeks. Which explanation best describes the relationship between resources (food) and population size, using evidence of cause and effect? (Remember: resources can limit population size.)
