Metabolic rate is the amount of energy used by an animal per unit of time.
Explanation:
About 70% of a human's total energy use is due to the basal life processes within the organs of the body. About 20% of one's energy use comes from physical activity and another 10% from the digestion of food after eating. All of these processes require an intake of oxygen to provide energy for survival usually from macronutrients like carbohydrates, fats, and proteins. Basal metabolism is usually by far the largest component of total energy used.
Broadly speaking, metabolic rate refers to how quickly fuels like sugars are broken down to keep the organism's cells running.
Metabolic rate varies with activity level. More active animals have a higher metabolic rate than less active animals. There are general differences in metabolic rate among species and the environmental conditions and activity levels of an individual organism will also affect its metabolic rate.
Thus, the amount of energy expended by an animal over a specific period of time is it's metabolic rate. It can also be termed as the rate at which our body burns calories.
