In this lab, the three flocks of birds changed in numbers between generation 1 and generation 3. Why? Check all reasons. The amo
unt of food available increased and decreased. If a flock’s beak type made it easier to pick up the available food, the flock grew. If a flock’s beak type made it harder to pick up the available food, the flock shrunk.
<u>Option-</u> "If a flock’s beak type made it easier to pick up the available food, the flock grew."
Explanation:
We can simplify the whole answer by having argument about the structure or alignment of the birds in a given way which provides more food sources or options for the 1st generation and then the third generation can be found in a more scattered form inside the herd, as there are no more food requirement as much was before.
