Biotic potential is the maximum reproductive or population-growth capacity under ideal conditions, with limiting factors absent and the intrinsic rate expressed fully. Actual populations rarely realize it because food shortage, enemies, weather, and competition impose environmental resistance. Actual conditions would therefore describe realized growth, not biotic potential. Parameters have clear roles: N is current abundance, r is the maximum per-capita rate under the model, and K is the positive equilibrium set by environmental capacity. The term 1 - N/K supplies negative feedback. Checking l
