  • Torpor
  • Torpor is often used to help animals survive during periods of colder temperatures, as it allows them to save the energy that would normally be used to maintain a high body temperature. (wikipedia.org)
  • Daily torpor, on the other hand, is not seasonally dependent and can be an important part of energy conservation at any time of year. (wikipedia.org)
  • Slowing metabolic rate to conserve energy in times of insufficient resources is the primarily noted purpose of torpor. (wikipedia.org)
  • Torpor enables animals to reduce energy requirements better survive harsh conditions. (wikipedia.org)
