Question

1. which component of energy output requires the greatest expenditure of the bodys energy?

basal metabolism
exercise
physical activity
the thermic effect of food

Explanation:

Basal metabolism is the energy the body expends at rest to maintain basic functions like breathing, circulation, and cell production. It typically accounts for the largest portion (about 60 - 75%) of total energy expenditure in most individuals. Exercise and physical activity (which includes non - exercise physical activity) together usually account for a smaller proportion (about 15 - 30%), and the thermic effect of food (the energy used to digest, absorb, and metabolize food) is the smallest component (about 10%).

Answer:

basal metabolism
