Temperature is one of the most important factors that affect an organism’s metabolic rates. In ectothermic organisms, their metabolic rate depends on the external environmental conditions. If temperature increases, so will their metabolic rates. Endothermic organisms do not depend on external conditions but rather can produce and maintain the generated heat within their systems to maintain their bodies at a constant temperature. If temperatures increase or decrease above or below the desired constant temperature or thermo neutral zone, these organisms have to do work and spend energy in order to reach a constant metabolic rate. The metabolic activity seen among both endothermic and ectothermic organisms varied in the different environmental

Thus for endothermic organisms, temperatures higher or lower than the organism’s thermo neutral zone temperature, or temperature tolerance range, require higher metabolic activities from the individuals. The results demonstrated that the mouse average rate of oxygen consumption increased at temperatures below its thermo neutral zone, because of the need to increase its body’s rate of heat production in direct proportion to the rate of heat that was being lost (Figure 1). At temperatures above the thermo neutral zone, the mouse had a dramatically lower metabolic activity because the ambient temperature in which it was placed did not require it to invest a vast amount of energy in order to adjust the conductance of the heat being lost. In the contrary, as poikilothermic endotherm organisms, gold fish are not able to produce a vast amount of heat from their metabolic activities. As a result, these organisms rely on the absorption of heat from their surroundings in order to regulate heat within their …show more content…
They are able to maintain a constant internal temperature by behaviorally adjusting their heat conduction in environments at different temperatures. Thus these organisms can be active at any time of day and live in a wide range of habitats. Although, the main disadvantage of an endothermic metabolism is that it is highly expensive. It requires a vast amount of energy input at both low and high temperatures environmental settings. Throughout involuntary movements, endotherms have to spend energy in order to allow their bodies to maintain their required constant temperatures. Ectothermic metabolisms such as the one of the goldfish are advantageous in the way that, they do not require a large input of energy for metabolic activity to occur. In the contrary, these organisms depend on the environmental conditions in order to regulate their body temperatures. The dependence on the environment’s temperature conditions for regulation puts them in disadvantage because as external temperatures fluctuate so do their internal body temperatures. These organisms do not have the ability of responding to involuntary movements in order to acquire the heat they lose to their surroundings. Thus, the dependence on external temperatures causes these organisms to have low metabolic
