Question

choose the correct answer.
in an age structure diagram, if there are more older individuals than younger ones, what population trend does it suggest?
no significant trend can be inferred
declining population
stable population
rapid population growth

Explanation:

In an age - structure diagram, the number of younger individuals (who will reproduce in the future) compared to older individuals (who are past their reproductive age) is crucial. If there are more older individuals, there will be fewer future reproductions. A declining population is indicated when there are not enough young individuals to replace the older generation as they die. A stable population has a relatively even distribution across age groups (with some variation for reproductive ages), and rapid growth has a large number of young individuals. Since more older than younger implies less future growth (as the young are the source of new population through reproduction), it suggests a declining population.

Answer:

declining population
