Flock X          57                            19%                                 6

Flock Y          153                           51%                                15

Calculations.

Food percentage:

Flock X = 57/300 * 100% = 19%

Flock Y = 153/300 * 100% = 51%

Flock Z = 90/300 * 100% = 30%

Simulated Number of Birds in Flock for 2nd Generation

Flock X = 19% * 30 = 6

Flock Y = 51% * 30 = 15

Flock Z = 30% * 30 = 9

because of

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
