How does a t-rex use energy?

Answer 1

A T. rex used energy primarily for locomotion, hunting, and maintaining its bodily functions. As a large carnivorous dinosaur, it likely expended energy while chasing prey or scavenging, relying on its powerful muscles and robust skeletal structure. Energy was derived from the food it consumed, primarily large herbivorous dinosaurs, which it metabolized to support its active lifestyle. Additionally, like modern reptiles, T. rex would have had periods of rest to conserve energy.
