This sounds like a question to something your teacher has just recently taught. I'm not sure how he/she wants you to answer but you a welcome to try; caloric intake and exercise frequency. Hope this helped.
This process is called osmosis
Fig reproduction and fig wasps are a common example used.
However, you're looking for two organisms so predator and prey. This could be Coyote and Deer, Lion and Gazelle... You name it.
The first integer as given in the question = m
Then
The second integer as described in the question = m + 3
Then the equation will be
m(m + 3) = 108
The correct option is option "A".
Now let us solve for "m"
m^2 + 3m - 108 = 0
m^2 + 12m - 9m - 108 = 0
m(m + 12) - 9(m + 12) = 0
(m + 12)(m - 9) =0
So the value of "m" is -12 and 9.
