Question

in the lab, you will change the number of birds with each beak phenotype for the second and third generations. what row of the data table will be the basis for computing new numbers?

Explanation:

The percentage of food eaten reflects a beak phenotype's fitness (ability to obtain food). Birds with beaks that eat more food are more likely to survive and reproduce, so this percentage helps predict how many birds with each phenotype will be in the next generations. It standardizes the data (removes absolute number biases) and shows relative success in resource acquisition, which drives natural selection - like processes in the lab simulation.

Answer:

The percentage of food eaten is good because it reflects a beak phenotype’s fitness (ability to acquire food). Higher percentages mean better survival/reproduction odds, so it predicts next - generation counts. It standardizes data (eliminates absolute number biases) and shows relative resource - acquisition success, driving the simulated selection process.
