Difficulty: Easy
Correct Answer: III, II, I, IV
Explanation:
Introduction / Context:
This question asks for a logical sequence of processes from taking in food to eliminating waste products.
Given Data / Assumptions:
Concept / Approach:
Order by physiological dependency: intake → breakdown → uptake → elimination.
Step-by-Step Solution:
Start with III Nutrition (ingestion).Then II Digestion (mechanical/chemical).Next I Absorption (transport into body fluids).Finally IV Excretion (waste removal).
Verification / Alternative check:
Absorption cannot precede digestion in a typical pathway; excretion is terminal.
Why Other Options Are Wrong:
Sequences with absorption before digestion or excretion mid-way violate basic physiology.
Common Pitfalls:
Confusing “nutrition” with “nutrition science”; here it denotes intake.
Final Answer:
III, II, I, IV
