1.Lag phase(A) - The organisms adapt itself in a new environment. Number of organisms remains same.
2.Log phase(B)- Population starts to double that is Number of organisms increases.
3.Stationary phase(C)- All the nutrients are depleted and growth rate becomes equal to death rate. And, finally all the organisms die due to lack of nutrients.
