Detailed Explanation
An idealised process of growth is divided into the lag phase, log phase and stationary phase.

The lag phase is the initial stage during which there is little or no growth.
Log of Numbers of Microorganisms
Time
The lag phase is followed by the log phase, during which the rate of growth is maximum(exponential).
Log of Numbers of Microorganisms
Time
During the stationary phase, the net growth rate remains stationary due to an equal rate of growth and death.

Senescence is the process by which an organism's growth slowly declines.
Dormancy is a period in an organism when growth and development are temporarily suspended.
