What is described by the exponential model of population growth?
1 Answer
Exponential model of population growth describes the volume of population (number of species) as an exponential function of time similar to:
where
Explanation:
Imagine you have bacteria that divides into 2 every hour.
If at
At any time
The above is a typical exponential growth of a population. The number of off-springs and other parameters can modify the formula, but it still will be based on exponential function with the time parameter in the exponent.
Obviously, real life conditions introduce complications in the formula based on variable productiveness and mortality rates.
