A desert lizard (an ectotherm ) and a mouse (an endotherm) are placed inside a chamber at `15^(@)C` and their body temperature [T(L) for the lizard and T(M) for the mouse] and metabolic rates [ML(L) for the lizard nad M(M) for the mouses] are monitored. Which one of the following is correct-A. T(L) and M(L) will fall while T(M) will increaseB. T(L) and M(L) will increase while T(M) and M(M) will fallC. T(L) and M(L) will fall, T(M) will remain same and M(M) will increaseD. T(L) and M(L) will remain same and T(M) and M(M) will decrease |

Answer» Correct Answer - C Desert lizard is an ectotherm (poikiliotherm ) whose body temperature vaires according to enviromental temperature . So, at `15^(@)C` T(L) will fal due ot fall in T(M) While mouse is a endotherm (Homeotherm) whose body temperature remains constant always due to variation is metabolic rate In homeotherms metabolic rate is inversely proportinal to enviromental tempertue. So at `15^(@)C` T(M) remain same and M(M) will increased. |
