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.

Answer 1

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.
