Question 1

What is a Population Growth?

Accepted Answer

Exponential population growth models how a population increases when resources are unlimited. P(t) = P₀ × e^(rt). Real populations are limited by carrying capacity.

Question 2

How does the Population Growth work?

Accepted Answer

P(t) = P₀ × e^(rt) Then: Doubling time T₂ = ln(2)/r ≈ 0.693/r Then: r = ln(Pt/P₀)/t Then: Negative r = population decline.

Question 3

Can you give an example of how to use the Population Growth?

Accepted Answer

Example: Input P₀=1,000 · r=0.05/yr · t=20yr gives a result of P(20) = 2,718 (1000×e^1.0=2718).
