Australian ecotherms and endotherms

Australian ect new(prenominal)ms and endotherms A- TYPES OF TEMPERATURE REGULATION 1- The cat, human and platypus could be described as licenced endotherms, as they all bind a relatively invariable internal personate temperature that is independent of the external temperature. As the surroundal temperature rises from 5C to 40C, the humans body temperature ashes constant, the cats and the platypus increases by around 3?C. 2- The lizard and echidna atomic number 18 ectotherms as their body temperature fluctuates fight to the temperature of the external environment. The lizards body temperature rises by 25C and the echidna by 10C as the external temp rises. 3- alone animals are either clear ectotherms or endotherms apart from the echidna. Although the body temperature of this animal increases with the external temperature, it does non increase as clearly as the lizards. An explanation for this could be that the echidna maintains a high level of energy to tramp over internal temperature than the lizard, which has a very limited mightiness to do so. 4- All enzymes and other molecules function within a limited temperature range. Unless the body temperature is maintained at these optimal conditions, the obtain of enzyme-catalysed reactions decreases and the organism will not function properly.
