Do Warm-Blooded Animals Need More Oxygen?
Warm-blooded or endothermic animals have high metabolic rates, requiring them to breathe in larger amounts of oxygen and eat more food to keep their body temperature up.
Why Birds And Mammals Need Still More Energy?
Answer: They have to produce heat for keeping their body warm. Birds and mammals are warm-blooded animals that maintain a constant body temperature irrespective of their surrounding temperature.Jan 30, 2020
Why Do Warm-Blooded Animals Use More Energy For Respiration?
‘Warm-blooded’ animals stay warm by producing heat energy. To make this heat energy the animal needs food and oxygen so that it can respire. Therefore when the weather becomes colder ‘warm-blooded’ animals breathe in more oxygen and eat more energy-giving food.
