Question

In the exponential growth equation:
$N_t=N_o{e}^{rt}$
What does "$t$" represent?

• A. Population density
• B. Growth rate or intrinsic rate of natural increase
• C. The base of natural logarithms
• D. Carrying capacity

Answer 1

The correct option is B

Growth rate or intrinsic rate of natural increase

In the equation
$N_t=N_o{e}^{rt}$
$N_t$ is the population size at time $t$
$N_o$ is the initial population size at $t=0$,
$t$ is time
$r$ is the population growth rate per capita or intrinsic rate of natural increase.
