Poikilotherms and homeotherms

WebSustained energy output of a poikilotherm (a lizard) and a homeotherm (a mouse) as a function of core body temperature. The homeotherm has a much higher output, but can only function over a very narrow range of body temperatures. Poikilotherm animals must be able to function over a wider range of temperatures than homeotherms. WebThat does not mean that poikilotherms can withstand wider environmental temperature ranges than homeotherms. If a poikilotherm is in an environment in which the temperature ranges from, say, 10° C to 30° C, its body temperature will vary acordingly (10° C-30°). If a homeotherm is in the same environment, its body temperature will be always ...

Endothermic and ectothermic animals: differences and examples

WebApr 28, 2014 · It was early observed that homeotherms increased their metabolic rate in cold environments (in order to maintain a relatively constant body temperature), but the metabolic rates of poikilotherms decreased in cold environments because of a decreased body temperature. WebIn contrast to the poikilotherms, whose vital processes depend entirely on external temperature conditions, homeotherms — birds and mammals — live at practically the same level of intensity during the entire year, and in all climatic regions; thus, they have a high level of reactivity, and can make use of their strengths and abilities whenever … merlin auto coupons https://austexcommunity.com
