If in a pond there were 150 carps found last year and through reproduction 450 new carps are added in the pond, what will be the birth rate here?

3 offsprings per carp per year

The correct answer is Option (2) -3 offsprings per carp per year

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.

If in a pond there were 150 carps last year and through reproduction 450 new carps are added, then the birth rate will be:

(450/150) =3 offsprings per carp per year
