Question

multiple choice question
endothermy requires an enormous amount of ____, which explains why birds and mammals must eat so much more food than ectotherms.
o speed
o strength
o cognitive power
o energy

Explanation:

Endotherms (birds and mammals) maintain a constant body temperature. This thermoregulation process requires a large amount of energy. They need to consume more food to obtain the energy necessary for metabolic processes that generate heat. Ectotherms, on the other hand, rely on external sources of heat and have lower energy requirements for thermoregulation.

Answer:

energy
