✅ The verified answer to this question is available below. Our community-reviewed solutions help you understand the material better.

There are three primary

macronutrients:

Carbohydrates (C): 4 Cal/g
Proteins (P): 5 Cal/g
Fats (F): 9 Cal/g

Fill in the blanks in the template files below so that together the files complete the following tasks:

1. Create a user-defined function, food

, that takes the amount of C, P, and F (in grams) as inputs, and

returns the total energy intake in both calories (Cal) and kilojoules (kJ).

Note that 1 Cal = 4.186 kJ. Assume that this function has been created in a user-defined module,

food_func.

2. Use this function to determine the energy intake for the following meals and display the results in a clear and readable format.

KFC snack plate: C = 55 g, P = 0.17 kg, F = 123 g
Dozen KK donuts: F = 131 g, P = 22 g, C =
0.275 kg
A 12-inch falafel sandwich: P = 14.7 g, F = 12.6 g, C = 1546.9 mg
