How should excretion be understood as different from digestion?
Answer and explanation
Correct answer: Excretion removes metabolic wastes while digestion breaks food
The governing concept is the distinction between nutrition and waste removal. Digestion is a nutritional process that mechanically and chemically breaks complex food into simpler, absorbable substances such as glucose and amino acids. Excretion removes wastes produced by metabolism, including nitrogenous wastes, excess salts, water, and carbon dioxide through appropriate organs. Therefore option A is correct; digestion does not itself mean urine formation, and the other choices confuse separate processes.
