Muscular system, gastrointestinal system and excretory system are required for the process.
Step-by-step explanation:
Cheetos is a nutrient rich diet which is actually a snack. Its a hard food, so needs to be chewed which uses the muscular system for chewing. The muscles of jaw like masseter and temporalis are required.
Now as the Cheetos are crunched, they need to be digested into finer particles and finally into the absorbable particles. This uses the gastrointestinal system. The enzymes digest the food and the villi of small intestine helps in the absorption.
The absorbed food are metabolized in liver and some excretory products are produced. They are excreted using the excretory system.
