About Population Growth Calculator
The Population Growth Calculator solves ecology problems using exponential growth (N(t) = N₀ × e^(rt)), logistic growth (dN/dt = rN(K−N)/K), and doubling time formulas. Enter your values and get step-by-step solutions with growth curve visualization.
Perfect for AP Biology and ecology coursework.
FAQ
Exponential growth occurs when a population grows at a constant rate without resource limitations: N(t) = N₀ × e^(rt).
Logistic growth models population growth with a carrying capacity (K). Growth slows as population approaches K: dN/dt = rN(K−N)/K.
Use the Rule of 70: doubling time ≈ 70 / growth rate (%). For exact calculation, use t = ln(2) / r.
