Question

In which phase population achieves zero growth?

(a) Growing phase

(b) Stationary phase

(c) Lag phase

(d) Log phase

I got this question during an interview for a job.

The above asked question is from Growth Models topic in section Organisms and Populations of Biology – Class 12

Answer 1

The correct choice is (b) Stationary phase

To explain: The population achieves zero growth in the stationary phase. It is the last phase of logistic growth. It is due to many reasons such as exhaustion of resources, aging, etc.
