When the ingredients are classified,
their calorie values will be mapped against the values stored in
the database. The calorie value obtained from level 1 (in this case
2000 Cal) is an approximate value for the average pizza without
considering its ingredients, and the calorie value obtained from
level 2 (in this case 2400 Cal) will be more accurate, as it takes
into account the ingredients. Hence, the results of the second level
testing will be the food object and its overall calorie value, 2400 Cal
in this case.
