Responses

thermogenesis because it takes energy to digest the food you eat and to store nutrients that contribute to energy use

basal metabolic rate (BMR) because the amount of energy used for a person’s movement can vary greatly

basal metabolic rate (BMR) because the amount of energy used for a person’s movement can vary greatly

basal metabolic rate (BMR) because it includes the energy used to keep the body’s systems functioning

basal metabolic rate (BMR) because it includes the energy used to keep the body’s systems functioning

thermogenesis because factors like age, sex, and body composition can influence a person’s energy requirements

Answer 1

basal metabolic rate (BMR) because it includes the energy used to keep the body’s systems functioning. BMR is the largest component of daily energy expenditure (≈60–70%) for basic physiological processes (organs, breathing, circulation, temperature regulation).
