Question

how would you describe the growth rate of a pyramid with a broad base?
a rapidly expanding population
a population with more old than young
a stable population
a population where natality equals mortality

Explanation:

A population pyramid with a broad base typically indicates a high birth rate. This means there are a large number of young individuals in the population. Such a population structure is characteristic of a rapidly expanding population. In a rapidly expanding population, the number of births (natality) is much higher than the number of deaths (mortality). Over time, this leads to an increase in the overall population size as more individuals are being added through births than are being lost through deaths.

Answer:

A rapidly expanding population
