Why are life processes considered essential for survival?
Answer and explanation
Correct answer: They handle energy material exchange and waste removal
Life processes maintain the conditions needed for an organism to remain alive. Nutrition supplies materials, respiration releases usable energy, transportation distributes substances, and excretion removes harmful metabolic wastes. Together these processes support growth, repair, regulation, and continuous cellular activity. Therefore A is correct. Changes in body size, colour, or sleep may occur in organisms, but none of these alone represents the essential set of life processes.
