What would be the per cent growth or birth rate per individual per hour for the same population mentioned in the previous question (Question 10)?

The correct option is B 200
Birth rate

Birth rate can be defined as the ratio between the number of individuals added (by birth) in an existing population and the initial population size, in a given time period.


$\text{Birth rate (b)}=\frac{\text{Number of individuals added}}{\text{Initial population}})$

Calculation of birth rate of Paramecium:

Birth rate of Paramoecium per hour can be calculated as follows :
Number of Paramoecium added in 1 hour = 100
Initial population size of Paramoecium = 50
Birth rate of Paramoecium = (100/50) x 100 = 200%

Final answer:
b.) 200
