Answer
Logistic growth: growth is limited.
Exponential growth$: $ growth is not limited.
Work Step by Step
Exponential growth model: $A=A_{0}e^{kt} \quad (k>0)$
(where $A_{0}$ is the initial quantity, and $A$ is the quantity after time t)
The growth is unlimited,
A can become arbitrarily large.
-----------
The logistic growth model, given by $A=\displaystyle \frac{c}{1+ae^{-bt}}$,
(a,b,c are constants and $c>0, b>0$)
describes situations in which growth is limited.
$y=c$ is a horizontal asymptote for the graph,
and growth, $A$, can never exceed $c$.
