The growth pattern of a population with an annual growth rate of 1.5% to 2.0% is
**Core Concept**
The growth pattern of a population with an annual growth rate of 1.5% to 2.0% is characterized by a slow and steady increase in the population size over time. This type of growth is often seen in developed countries with low birth rates and high life expectancy.
**Why the Correct Answer is Right**
The S-shaped curve, also known as the logistic growth curve, is a mathematical model that describes this type of growth pattern. The curve starts slowly, accelerates in the middle, and then levels off as the population approaches its carrying capacity. This type of growth is influenced by factors such as birth rates, death rates, and immigration/emigration rates.
**Why Each Wrong Option is Incorrect**
**Option A:** Exponential growth is characterized by a rapid increase in population size, which is not consistent with the slow and steady growth pattern described in the question.
**Option B:** This option is not relevant to the description of population growth patterns.
**Option C:** This option is not relevant to the description of population growth patterns.
**Clinical Pearl / High-Yield Fact**
It's essential to note that population growth patterns can have significant implications for healthcare planning, resource allocation, and public health policy.
**Correct Answer: D. Logistic growth.**
