How are digestion, respiration, transport and excretion connected in life processes?
Answer and explanation
Correct answer: Digestion gives nutrients, respiration gives energy, transport carries them and excretion removes wastes
Life processes work as an integrated system. Digestion breaks complex food into absorbable nutrients such as glucose. Respiration uses these nutrients, especially glucose, to release energy. The transport system carries nutrients and oxygen to cells and moves wastes away. Excretion removes metabolic wastes and helps maintain internal balance. Thus option A correctly describes their connection; the remaining options deny or misassign these functions.
