Calculate the birth rate if there were 60 sparrows in a garden last year and through reproduction 24 new sparrows are added this year ? |
0.4 offsprings per sparrow per year 0.2 offsprings per sparrow per year 0.6 offsprings per sparrow per year 0.1 offsprings per sparrow per year |
0.4 offsprings per sparrow per year |
The correct answer is Option ( 1) -0.4 offsprings per sparrow per year To calculate the birth rate, you need to find the average number of offspring produced per sparrow per year. You can do this by dividing the total number of new sparrows added this year by the number of sparrows in the garden last year: Birth Rate = (Number of New Sparrows) / (Number of Sparrows Last Year) Birth Rate = 24 / 60 Birth Rate = 0.4 So, the birth rate is 0.4 offspring per sparrow per year, which corresponds to option (1): "0.4 offsprings per sparrow per year."
