If most individuals in a population are young, why is the population likely to grow rapidly in the future?
a. Death rates will be low.
b. The population has a skewed age distribution.
c. Immigration and emigration can be ignored.
d. Many individuals will begin to reproduce soon.

검증된 단계별 안내

Understand the concept of age distribution in a population. A population with a large number of young individuals typically indicates a potential for future growth.

Consider the reproductive potential of young individuals. As these individuals mature, they will reach reproductive age, leading to an increase in birth rates.

Analyze the impact of low death rates among young individuals. Young populations generally have lower mortality rates, contributing to population growth.

Evaluate the role of immigration and emigration. While these factors can affect population size, the presence of many young individuals suggests internal growth through reproduction.

Recognize the significance of option d: 'Many individuals will begin to reproduce soon.' This is a key factor in predicting rapid population growth, as the young individuals will contribute to the next generation.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Age Structure

Age structure refers to the distribution of individuals of different ages within a population. A population with a large proportion of young individuals suggests a potential for rapid growth, as these individuals will soon reach reproductive age, increasing the birth rate and contributing to population expansion.

Reproductive Potential

Reproductive potential is the capacity of a population to grow based on the number of individuals capable of reproducing. Young populations have high reproductive potential because many individuals will soon enter their reproductive years, leading to an increase in birth rates and, consequently, population growth.

Population Growth Rate

Population growth rate is the change in the number of individuals in a population over time. It is influenced by birth rates, death rates, and age distribution. A population with many young individuals is likely to experience a high growth rate as these individuals mature and reproduce, assuming other factors like death rates remain constant.
