Why is maintaining a high body temperature (e.g. 37°C) more challenging for smaller endothermic animals than for larger endothermic animals? Smaller animals have a lower metabolic O rate (per gram of body mass) relative to larger animals. Smaller animals have a higher surface area O to volume ratio and therefore lose greater amounts of heat to the environment. Smaller animals have lower surface area to O volume ratio and therefore lose greater amounts of heat to the environment. O Smaller animals are unable to produce fatty tissue for insulation. Smaller animals are unable to shiver at a O rate that is fast enough to produce heat in their muscles. O Smaller animals are ectoderms while larger ones are endoderms Smaller animals always have thinner fur

An animal living in a cold environment loses heat at a rate that is proportional to its surface area, but its metabolism generates heat in all of its cells, so the rate of heat generation is proportional to its volume. All other factors being equal (which they often are not!), which implications would follow from these facts? Choose all correct responses. Because it is smaller, a baby seal is more at risk for hypothermia (body temperature falling to too low a value) than is an adult when it is in an ocean significantly colder than its body temperature. If you take a baby outdoors on a cold day, you should dress it more warmly than you would dress yourself because it is smaller. If you take a baby outdoors on a cold day, you should dress it less warmly than you would dress yourself because it is smaller. If you take a baby outdoors on a cold day, how cold it feels to you is a good measure of how warmly you should dress that baby. Because it is smaller, a baby seal is less at…
