not doing your homework for you, but I'll give you a pointer:
Most organisms have an age range where they can reproduce effectively. Individuals who have not matured yet, or who have just barely matured, will generally not reproduce. Individuals who are nearing the end of their natural lifespans (barring semelparous species) don't reproduce very much.
Also, most species have high death rates at very young and/or very old ages. Before the industrial era, a population composed mostly of newborn infants would very soon become a much smaller population, because the death rate for young children was close to 50%.
So, if you know the reproduction rate, and the death rate, of individuals of various ages, you will also know the potential for growth.
