Breaking down a burger in the stomach.

Explanation:

Basal metabolic rate (BMR) also known as resting metabolic rate (RMR) can be defined as the amount of calories that is required to keep the human body to function properly and perfectly at rest.

This ultimately implies that, basal metabolism is the minimal amount of calories or energy that is required by an individual for maintaining vital functions such as blood circulation, keeping the body warm and respiration while fasting or in a complete mental and physical rest.

Some of the factors that affects the basal metabolism rate (BMR) in humans are height, weight, age, starvation or fasting, thyroxine, fever, stress, malnutrition and growth.

Hence, breaking down a burger in the stomach is a body function that would contribute to BMR.
