Question

Figure 52.9 
-Figure 52.9 shows the age structure of Common Primrose populations as they change over time.One of the populations is growing under high light conditions and the other under low light.Based on the graphs in Figure 52.9,which graph,(a)or (b),represents a population growing in high light availability?

Quizplus · Accepted Answer

The graph (a) shows a larger percentage of individuals in the younger age classes, with a sharp decline in the older age classes, indicating a population that is growing quickly. This is likely to occur under high light conditions, where plants have access to more resources and can grow faster. The graph (b) shows a more even distribution of individuals across the age classes, indicating a population that is not growing as quickly. This may occur under low light conditions, where plants have limited resources and grow more slowly. Therefore, based on the age structure data, option (a) is the best choice for representing a population growing in high light availability.
