Endotherms
Main article:
EndothermTo regulate body temperature, an
organism may need to prevent heat gains in arid
environments.
Full article >>>Endotherms include birds,
mammals, and insects. The advantages of
endothermy are increased
enzyme activity and a constant body temperature, allowing these
animals to be active in cold temperatures.

animals — birds and
mammals — that generate internally the heat needed to maintain their body temperature.

action that gives off energy. The product is in a lower energy state than the reactants.
endotherms
Animals that have the ability to maintain a constant body temperature over a wide range of
environmental conditions.
Full article >>>endotherm(en-doh-thurm) [Gk. endon, within + therme, heat]
An
animal that uses metabolic energy to maintain a constant body temperature, such as a bird or mammal. See also Homeotherm.
Full article >>>endotherm (or homeotherm)An
organism that can regulate its internal temperature. Compare
ectotherm.
endothermic Having a body temperature determined by heat derived from the
animal's own oxidative
metabolism; contrasts with
ectothermic.
