Under ideal conditions, the growth of a population of bacteria occurs in several stages termed lag, log, stationary, and death.
During the lag phase, active metabolic activity occurs involving synthesis of DNA and enzymes, but no growth.
Geometric population growth occurs during the log, or exponential phase, when metabolic activity is most intense..
Following the log phase, the growth rate slows and the production of new cells equals the rate of cell death. This period, known as the stationary phase, involves the establishment of an equilibrium in population numbers and a slowing of the metabolic activities of individual cells. The stationary phase reflects a change in growing condition—for example, a lack of nutrients and/or the accumulation of waste products.
When the rate of cell deaths exceeds the number of new cells formed, the population equilibrium shifts to a net reduction in numbers and the population enters the death phase, or logarithmic decline phase. The population may diminish until only a few cells remain, or the population may die out entirely.

The exponential phase.

The 5 phases are:

1. Lag phase

2. Exponential phase (Log)

3. Stationary phase

4. Death phase

5. Prolonged decline and/or (death) phase

It would be exponential phase.

Lag phase- steady bacterial growth Log phase- exponential bacterial growth Stationary phase- growth levels off Death phase- bacteria begins to die away

First stage= Lag phase

Second stage= log, or exponential growth, phase

Third stage= Stationary phase

Forth stage= Death, or logarithmic decline, phase
