To solve this problem, we need to analyze the population structure described in the options. A growing population typically has certain characteristics. Let's evaluate each option:$\newline \bullet$Option 1: Reproductive and pre-reproductive individuals are equal in number.$\newline$ - In a growing population, the number of pre-reproductive individuals is usually higher than the number of reproductive individuals.$\newline$ - Therefore, this option does not describe a growing population.$\newline \bullet$Option 2: Reproductive individuals are less than the post-reproductive individuals.$\newline$ - In a growing population, the number of reproductive individuals is typically higher than the number of post-reproductive individuals.$\newline$ - Hence, this option does not describe a growing population.$\newline \bullet$Option 3: Pre-reproductive individuals are more than the reproductive individuals.$\newline$ - A growing population is characterized by a larger number of pre-reproductive individuals, indicating potential for future growth.$\newline$ - This option accurately describes a growing population.$\newline \bullet$Option 4: Pre-reproductive individuals are less than the reproductive individuals.$\newline$ - This scenario is more typical of a stable or declining population, not a growing one.$\newline$Therefore, the correct option is Option 3, as it correctly describes the characteristics of a growing population.
