Differentiate between Ectotherms and Endotherms.

(N/A) The differences between Ectotherms and Endotherms are as follows:
$1$. Definition: Ectotherms are organisms that rely on external environmental heat sources to regulate their body temperature,whereas Endotherms are organisms that generate their own internal metabolic heat to maintain a constant body temperature.
$2$. Metabolic Rate: Ectotherms have a lower metabolic rate compared to Endotherms.
$3$. Environmental Dependence: Ectotherms are highly dependent on the ambient temperature for their physiological activities,while Endotherms can remain active across a wider range of environmental temperatures.
$4$. Energy Requirement: Ectotherms require less food energy because they do not spend energy on thermoregulation,whereas Endotherms require a high amount of energy to maintain a constant body temperature.
$5$. Examples: Ectotherms include reptiles,amphibians,and most fish. Endotherms include birds and mammals.
