Which of the following is not correct with reference to exponential growth model?

Options

  1. AResources are limited
  2. BPopulation grows in a geometric fashion
  3. CA stationary phase is never reached
  4. DPopulation grows beyond carrying capacity

Correct answer

A. Resources are limited

Step-by-step solution

The exponential growth model assumes that resources (food and space) are unlimited in the habitat. Therefore, the statement that resources are limited is incorrect for this model. Under ideal, unlimited resource conditions, the population grows in an exponential or geometric fashion, following the equation dN dt = rN . Because resources are never depleted in this theoretical model, the population continues to grow indefinitely, meaning a stationary phase is never reached. Answer: Resources are limited
