Model exponential and logistic population growth. Project how a population changes over multiple generations using standard ecological growth equations.
Model exponential and logistic population growth. Enter starting population, growth rate, and carrying capacity to project how a population changes over time.
Exponential: N(t) = N₀ × eʳᵗ. Logistic: N(t) = K / (1 + ((K−N₀)/N₀) × e^(−rt)).
Exponential vs logistic growth
Exponential growth assumes unlimited resources and produces a J-curve. Logistic growth accounts for a carrying capacity K and produces an S-curve. Real populations usually follow logistic growth because resources are finite.
