Answer:
0 change in population. I think.
Explanation:
first we are adding 32 ants to the total because 32 ants were born so 1000+32 = 1032.
Next we are subtracting 32 ants from the new total because a pesticinde was used in the area. So 1032 - 32 is 1000. 1000 was the original total so there was not a decrease in popualtion or an increase.
