An animal’s metabolic rate determines how much food it must consume to maintain its body at a constant mass. If an animal doesn’t eat enough food to replace the energy it uses up, it will lose body mass (as glycogen, fats, and other macromolecules are burned for fuel).
What affects animal metabolism?
The two factors underlying most of this variation are well known: body mass and higher-level taxonomic affiliation. … (Metabolic rate per g of body mass decreases with body mass but by a power smaller than 1.0, so the absolute metabolic rate of a whole animal, the subject of this paper, increases with mass).
What is metabolism easy definition?
Metabolism (pronounced: meh-TAB-uh-liz-um) is the chemical reactions in the body’s cells that change food into energy. Our bodies need this energy to do everything from moving to thinking to growing. Specific proteins in the body control the chemical reactions of metabolism.
What animal has the highest metabolism?
Hummingbirds, with their tiny bodies and high levels of activity, have the highest metabolic rates of any animals — roughly a dozen times that of a pigeon and a hundred times that of an elephant. To maintain those rates, hummers have to consume about their weight in nectar daily.

Why do hummingbirds have such a fast metabolism?
The hummingbird heart rate is high and it’s pumping so much blood per unit of time. They have lots and lots of capillaries that allow the blood to get up close and personal to their muscle cells. And hummingbirds can apparently take up fructose in their cells, and we’re trying to figure out what enables that.
What is a sloths metabolism?
Sloths have very low metabolic rates (less than half of that expected for a mammal of their size), and low body temperatures: 30 to 34 °C (86 to 93 °F) when active, and still lower when resting.
What does exercise do to your rate of metabolism?
Amount of physical activity – hard-working muscles need plenty of energy to burn. Regular exercise increases muscle mass and teaches the body to burn kilojoules at a faster rate, even when at rest. Drugs – like caffeine or nicotine, can increase the BMR.
