Question

The equation $\frac{∆ N_{n}}{N ∆ t}$ = B represents, which of the following?

Natality

Growth rate

Mortality

All of these

Solution

Natality

Natality or birth rate is the rate of production of new individuals per unit of population per unit time through birth. Natality is expressed as $\frac{∆ N_{n}}{∆ t}$ and $\frac{∆ N_{n}}{N ∆ t}$ = Specific natality rate.
