Question

19 multiple choice 2 points in the exponential growth model, the population growth rate is proportional to: environmental resistance the death rate the current population size the number of predators present

Explanation:

The exponential growth model is represented by the equation \( \frac{dN}{dt}=rN\), where \( \frac{dN}{dt}\) is the population growth rate, \( r\) is the intrinsic rate of increase, and \( N\) is the current population size. This shows that the population growth rate is directly proportional to the current population size. Environmental resistance, death rate, and number of predators are factors that are not part of the basic exponential growth model's proportional relationship (the exponential model assumes no limiting factors like these in its simplest form).

Answer:

The current population size.
