Question

question 2
basal metabolism includes energy needs for
○ breathing and circulating blood.
○ performing physical activity.
○ digesting food.
○ absorbing nutrients.

Explanation:

Basal metabolism refers to the minimum energy expenditure of an organism at rest to maintain basic life - sustaining functions. Breathing (to supply oxygen for cellular respiration) and circulating blood (to transport nutrients and oxygen to cells and remove waste) are fundamental life - sustaining processes that occur at rest. Physical activity (requires additional energy above basal), digesting food (is part of the thermic effect of food, not basal), and absorbing nutrients (is part of the digestive process which is not basal) are not part of basal metabolism.

Answer:

breathing and circulating blood.
