Question

simulate changes in flock size
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
bethe basis for computing new numbers?
number of insects eaten
number of seeds eaten
number of fruit eaten
total food eaten eaten by the flock
percentage of food eaten by the flock

Explanation:

To compute new numbers for the second and third generations of birds with each beak phenotype, we need the data that reflects the current state of the flock in terms of food consumption which is related to their survival and reproduction (as more food eaten can imply better chances of survival and thus contributing to the next - generation numbers). The percentage of food eaten by the flock (for each beak phenotype) gives a relative measure of how successful (in terms of food acquisition) each beak type is. This relative measure (percentage) can be used to scale and calculate the new numbers of birds in the next generations.

Answer:

Percentage of food eaten by the flock
