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

Answer 1

The correct option is D Birds

• Birds have high basal metabolic rates. As with metabolic rates, birds tend to have higher body temperatures than mammals. In general body temperatures of birds ranges from about 38-42 degrees Celsius.
  
• Birds have limited fat reserves because in cold weather these warm-blooded animals burn the fat to maintain their body temperature.
  

Because of these reasons birds make a large requirement of food high in energy value.
