Who published the logistic equation model of population growth in 1838?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Pierre François Verhulst.
The logistic equation model of population growth was published by Pierre François Verhulst in 1838.
Verhulst, a Belgian mathematician, introduced this S-shaped curve to describe how populations grow rapidly at first but slow as they approach a maximum limit (carrying capacity).
His work expanded on Thomas Malthus’ exponential growth theory by incorporating environmental constraints. The logistic equation later became fundamental in ecology and population dynamics.
