Which of the following is a physiological need related to elimination of waste?

Explanation:
Elimination of waste is handled by excretion. This process removes metabolic wastes such as urea, excess salts, and water from the body, primarily through the kidneys (urine), digestive tract (feces), and skin (sweat). Ingestion is about taking in nutrients, not removing waste. Respiration does involve removing a waste product (carbon dioxide) but the broader term for waste elimination is excretion. Reproduction isn’t related to waste elimination. So excretion is the best-fit physiological need for removing waste.
