उत्तर
In a pond, the birth rate of a lotus plant is calculated by dividing the increase in the number of plants by the initial number of plants.
Given:
Initial plants = 40,
After a year = 56,
The increase = 56 − 40 = 16
Thus,
Birth rate = `16/40`
= 0.4 offspring per lotus plant per year.
This means each lotus plant produces 0.4 new plants on average annually.
