Question

during one year a population of blue jays has zero population growth. which must be true about the blue jay population at the end of the year compared to the beginning of the year?
○ it will have the same number of individuals in it.
○ it will have the very same individuals in it.
○ it will have become larger.
○ it will have become smaller.

Explanation:

Zero population growth means the total number of individuals in a population remains unchanged over a given period. This accounts for births balancing out deaths, and any immigration balancing emigration, so the total count stays the same. The specific individuals in the population can change (due to births, deaths, movement), but the total number does not.

Answer:

A. It will have the same number of individuals in it.
