The growth of a population per unit time is calculated by using this formula: G = r × N. What is the quantity r and how is it calculated?
A) The quantity r is the exponential growth rate and is calculated by subtracting the number of deaths from the number of births.
B) The quantity r is the per capita growth rate and is calculated by multiplying the number of births and the number of deaths.
C) The quantity r is the per capita growth rate and is calculated by subtracting the number of deaths from the number of births.
D) The quantity r is the biotic potential of a population and is calculated by adding the birth rate and the death rate.
E) The quantity r is the monthly net increase of a population and is calculated by subtracting the number of births from the starting population size.
Per Capita Growth Rate
Refers to the rate of population growth per individual within a given time frame, often used to assess changes in population size relative to the current population.
Exponential Growth Rate
Exponential Growth Rate describes the increase of a quantity by a consistent rate over proportional time intervals, commonly observed in populations lacking resource limitations.
Biotic Potential
The maximum reproductive capacity of an organism under optimal environmental conditions, reflecting the potential for population growth.
- Determine and describe the patterns evident in population development, and the determinants of these patterns, inclusive of exponential and logistic growth.

Final Answer :
C
Explanation :
The quantity r is the per capita growth rate and is calculated by subtracting the number of deaths from the number of births. This means that r represents the rate at which the population is increasing per individual, and is based on the difference between the birth rate and the death rate.
