Question

In which group, high regulated body temperature and limited fat reserve, make a large requirement of food high in energy value
A)Mammals
B)Fishes
C)Reptiles
D)Birds

Answer 1

Hint: Thermoregulation is a process by which mammals regulate body temperature independent of external temperatures with closely regulated self-regulation. Regulation of temperature is a type of homeostasis and a way of maintaining a stable internal temperature to survive.

Complete answer:
There are high basal metabolic rates in birds. As with metabolic rates, birds are more likely than humans to have higher body temperatures. The body temperature of birds usually varies from around 38-42 degrees Celsius. Birds have small stores of fat and these warm-blooded animals burn fat to preserve their body temperature in cold weather. Because of these causes, birds need a significant volume of food high in energy content.

Endothermic birds and mammals. People have an internal core temperature of about 37 degrees Celsius using a rectal probe thermometer (98.6 degrees Fahrenheit). This is the ideal temperature of the human body's functions. Thermo-regulation is important for human survival. Without thermo-regulation, the human body fails to function. In the body's response to infectious diseases, thermo regulation also plays an adaptive function.

Hence, the correct answer is option (D)

Note: Three separate thermal modulation pathways exist: afferent sensing, central control and successful replies. The heat and cold receptors are available in the human body. Afferent signaling is used to decide if the central body temperature from these receptors is too warm or cold. Hypothalamus is the gateway to thermo-regulation.
