Question

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

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

Answer 1

The correct option is D 100 per hour

Growth rate of a population can be defined as the increase in number of individuals in a population per unit time.

No. of individuals of Paramoecium in the initial population = 50

No. of individuals of Paramoecium in the final population after an hour = 150

Population growth rate

= (Final population size - Initial population size)/Time taken for population change

= (150-50) Paramoecium/hour

Thus, the growth rate of the Paramoecium population is 100 Paramoecium per hour.
