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.

Answer 1

The population will be less as some will die or there are chances of equal also if no one died... Most chances are of 1st one. But it also must be the same or less. Depending on if population growth means just how much it got bigger of if it can be negative (like -8% means it got smaller by 8% and being considered "growth").

Hope this helps!

Answer 2

Answer:

Option A, It will have the same number of individuals in it

Explanation:

When it is said that the population growth is zero, then it means that the number of people/individuals in a population remains same.

Or Population growth is zero when equal number of individual have died and taken birth at the same time.

For example -

Suppose the population of Blue jay a year ago was 1000, out of this 20 died after one month. In the remaining 11 months , 20 new individuals were born. Then, population growth of blue jay would be -

$1000- 20 -( 1000 + 20)\\= 1000$

Hence, option A is corect
