Practice question · Multiple choice
Logistic growth adds a carrying capacity to exponential growth. Why does that change the long-run forecast so drastically when both start identically?
Hints
- Ask what happens to the growth term as the population approaches .
- Which of the two ever stops growing?
Show the answer
D. Because the growth rate is scaled by how much room is left
Why
Both fit early data well, which is what makes the choice dangerous: the model, not the data, is doing the forecasting once the ceiling starts to bite.
