Based on the diagram below, it can be observed that a yougurt basically compraises of two primary ingredients, that is milk and live bacteria.
To begin with, the milk is initially heated up to the temperatures of 90C (200F) for around 30 mins. More the time, the thicker the yougurt gets, hence it can be observed that time plays an important factor in the constituency of the yougurt.
The second steps is followed by cooling the milk to lower temperatures around 44C(112F). Once the milk reaches the desired temperature, live bacterias are added to the milk evenly.
The next step is leaving the mixture at room temperature, optimally around 37C for atleast 4 hours. At this stage, it can be observed that the live bacteria tends to react with the milk, in process of turning the milk into think liquid.
Following this, the mixture is cooled in refridgerator. Once cooled, the mixures turns into plain yougurt. Some additives can be added to the freshly prepared yougurt such as sugar and nuts.
Lastly, the mixture is poured into small cups and ready to be shipped. Hence, the process above diagram briefly describes the simple procedure to prepare a yougurt from milk in seven steps. 
Based on the diagram below, it can

To  
begin
 with, the  
milk
 is  
initially
 heated up to the  
temperatures
 of 90C (200F) for around 30  
mins
. More the time, the thicker the  
yougurt
  gets
,  
hence
 it can  
be observed
 that time plays an  
important
 factor in the constituency of the  
yougurt
.
The second steps  
is followed
 by cooling the  
milk
 to lower  
temperatures
 around 44C(112F). Once the  
milk
 reaches the desired  
temperature
,  
live

The
