The exponential growth model illustrates a growth pattern characterized by an increase at a constant rate, which results in a "J" shaped curve when graphed over time. In this model, the population grows rapidly as resources are abundant, leading to a doubling effect where the number of individuals increases exponentially rather than linearly.

This growth occurs because each generation produces more individuals, and as the population becomes larger, the rate of growth becomes even faster. This phenomenon is typical in environments where conditions are ideal, and resources such as food, space, and mates are plentiful. The "J" shaped curve visually represents this rapid increase followed by potential limits when resources eventually become scarce, leading to a slowing of growth or a decline.

In contrast, gradual increases in population might indicate a more stable, linear growth pattern, while a constant pace of decline signifies a reduction in population rather than growth. A stable population with no major fluctuations suggests a balance between birth and death rates, not an exponential increase. Understanding the characteristics and implications of exponential growth is vital, especially in ecology and conservation biology.
