Birth rate in a population is calculated as: (a) Increase in numbers with respect to members of the population

The birth rate in a population is a measure of the rate at which new individuals are added to the population through reproduction. It indicates the reproductive capacity and potential growth of the population. To calculate the birth rate, we consider the increase in numbers with respect to the total members of the population.

For example, let's consider a population of rabbits. If there were 100 rabbits at the beginning of the year and, by the end of the year, the population increased to 150 rabbits due to reproduction, we can calculate the birth rate as follows:

Birth Rate = (Increase in numbers / Total population) * 100 = ((150 - 100) / 100) * 100 = 50%

In this case, the birth rate is 50%, indicating that the population increased by 50% over the course of the year.

The birth rate is an important parameter in population ecology as it helps us understand the reproductive success and potential growth of a population. It provides valuable insights into the dynamics of population size and the impact of reproduction on population demographics.
