The word metabolism comes from a Greek word that means "a change." Metabolism can be defined as the sum of the nutritional and waste processes of an organism. This involves the digestion, use, and excretion of food. Studies have shown that an animal's metabolism is affected by the climate; warm-blooded animals have slower metabolisms at warmer temperatures.
