Question
The number of lily plants in a pond was found to be 50. After one year, the number. increased to 65. Calculate the natality of lily plants.
Solution
Given that the initial number of lily plants was 50 and increased to 65 after one year, the population increase is 65 − 50 = 15 plants. The time period is 1 year. So, the calculation is:
`"Natality Rate" = "Increase in Population"/"Original Population" × "Time Period"`
`"Natality Rate" = 15/50 × 1`
`"Natality Rate" = 15/50`
`"Natality Rate" = 0.3`
This means the pond's lily plants have a natality rate of 0.3 per plant per year.
