Question

Compare and contrast exponential growth and logistic growth

Plot N vs time for both models

Plot dN/dt vs. N for both models

Plot b and d vs. N for both models

Then

Compare and contrast geometric growth and exponential growth

Definitions of r

Definitions of lambda

Relation between r and lambda

Lambda = 1.0 for population of constant size

r = 0 for population of constant size

Doubling time formula

Plot dN/dt(1/N) for both models

Identify r, K, and MSY (where N=K/2) where ever possible on these plots

Exponential growth occurs when the sources are not limiting. The curve obtained is known as J shaped curve.

Logistic growth occurs when sources are limiting. The curve obtained is sigmoid or S shaped.
