If a population of 50 Paramecium present in a pool increases to 150 after an hour, what would be the growth rate of population ?

Options

A. 50 per hour
B. 200 per hour
C. 5 per hour
D. 100 per hour

Answer

To calculate the growth rate of the Paramecium population, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Initial and Final Population**:
- Initial population (P0) = 50 Paramecium
- Final population (P1) = 150 Paramecium

2. **Calculate the Change in Population**:
- Change in population (ΔP) = Final population - Initial population
- ΔP = P1 - P0
- ΔP = 150 - 50
- ΔP = 100 Paramecium

3. **Determine the Time Period**:
- The time period (t) over which this change occurred is given as 1 hour.

4. **Calculate the Growth Rate**:
- Growth Rate (R) = Change in Population / Time Period
- R = ΔP / t
- R = 100 Paramecium / 1 hour
- R = 100 Paramecium per hour

### Final Answer:
The growth rate of the Paramecium population is **100 Paramecium per hour**.
