Lag phase, log phase, stationary state phase, and death phase
Explanation:
The first phase is lag phase. The population is almost constant and bacteria are being waiting.
The second phase is log phase. Population increases rapidly (as exponential growth) until resources or conditions become limited.
The third phase is stationary phase. Population stays stable, there is no decrease or increase in population.
Finally death phase exists. In this stage death of bacteria occurs (due to wastes, not favourable conditions, etc.).
