Question

Go through the population growth formula $\frac{dN}{dt}=rN$. Now select the correct option:

• A. As population gets larger, its rate of growth increases
• B. Represents growth as a continuous process
• C. r is constant and N is variable
• D. All of the above

Answer 1

The correct option is D All of the above

Almost all populations tends to grow expotentially as long as the resources are available. The given formula is for the exponential growth of a population.
In the given equation,
N- number of existing individuals (variable)
r- intrinsic growth rate (constant)
t- time
dN/dT- rate of change of population size
