Question
In a short passage of 1-3 paragraph, answer the following question What are the disadvantages of obligate endothermic homeothermy, relative to the facultative poikilothermic ectothermy by many species of lizards and snakes? In what environments would you expect obligate endothermic homeotherms to have the most significant advantages, and in what environments might faculties poikilothermic ectotherms have an edge? Produce a hypothetical figure of temperature (X axis) vs O2 consumption, (Y axis) for a hypothetical endothermic homeotherm vs a hypothetical ectothermic poikilotherm, and insert it into this document. Produce a table listing at least ten species that pursue each lifestyle, including scientific names, and environment in which they live. Insert it into this document.Explanation / Answer
obligate endothermic homeotherms are organisms that maintain their body temperature by internally generated body heat.Examples include mammals.Obligate endothermic homeotherms cannot survive in sub zero temeratures because the body temerature has to be maintained by metabolically produced heat energy and there are not sufficient resources available in those conditions to support survival.
Obligate endotherms can survive well in enviroments where there is adequate supply of food because they utilize the energy from metabolism to maintain their body temperature.Ectothermic poikilotherms can survive well in desert environment where there is scarcity of food,but they maintain they body temperature through solar radiation.
examples of obligate endotherms with their scientific names:
humans-homo sapiens,mouse-Mus musculus,dog- Canis lupus familiaris,cat-Felis catus,cow-Bos taurus,goat-Capra aegagrus hircus,sheep-Ovis aries,horse-Equus caballus,tiger- Panthera tigris,lion- Panthera leo
examples of ectothermic poikilotherms with scientific names:
lizard- Lacertilia, frog- Rana temporaria, crocodile- Crocodylinae, Chameleon- Chamaeleonidae, Turtle- Testudines, alligator-Alligator mississipiensis, gecko -Hemidactylus franatus, Iguana-Iguana iguana, Tortoise- Testunidae,salamander- Caudata
