1. They are related as such that growth rate drives population size and population size influences growth rate.
2. Analyzing the population size curve reveals trends like exponential growth, plateaus, or even declines.
1.
The upward slope of the population size curve closely follows the fluctuations in the growth rate curve. This indicates that periods of high growth rate directly translate to rapid increases in the overall population size. Conversely, dips in the growth rate curve coincide with slower or even negative population growth.
2.
The information helps us understand the overall trajectory of the human population and identify potential issues like overpopulation or population decline in specific regions. By knowing the size, we can calculate metrics like population density and resource consumption, providing valuable insights into societal and environmental pressures.
