Australian ecotherms and endotherms

Australian ectotherms and endotherms A- TYPES OF TEMPERATURE REGULATION 1- The cat, human and platypus could be set forth as accredited endotherms, as they all maintain a relatively unbroken internal body temperature that is independent of the international temperature. As the environmental temperature rises from 5C to 40C, the humans body temperature remains constant, the cats and the platypus increases by around 3?C. 2- The lizard and ant bear be ectotherms as their body temperature fluctuates match 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- All wights are either clearly ectotherms or endotherms apart from the echidna. Although the body temperature of this animal increases with the external temperature, it does not increase as clearly as the lizards. An explanation for this could be that the echidna maintains a higher level of energy to avow over internal temperature tha n the lizard, which has a actually limited ability to do so. 4- All enzymes and other molecules subprogram within a limited temperature range. Unless the body temperature is maintained at these optimal conditions, the pose of enzyme-catalysed reactions decreases and the organism will not work out properly.
