If there were 100 rose plants in a garden last year. 20 new rose plants are added through reproduction in current year. The birth rate of rose is____________ offspring per rose per year.

0.2

The correct answer is Option (4) -0.2

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.

 There were 100 rose plants in a garden last year . 20 new rose plants are added through reproduction in current year. The population increased to 120 rose d we can calculate the birth rate as follows:

Birth Rate =20 /100 = 0.2
