What contributes the most to energy need?​

Quizplus · Accepted Answer

Basal metabolism, also known as resting energy expenditure, contributes the most to energy need as it is the energy required to maintain basic physiological functions at rest. It can account for up to 60-80% of daily energy expenditure, while physical activity and dietary thermogenesis typically contribute 20-30% and 10% respectively. Digestion and nutrient storage also require energy, but to a lesser extent than the other factors listed.
