What factor related to its large body size made a highly energetic hunting lifestyle difficult for *Gastornis* to sustain?
Answer
High metabolic cost
Maintaining a large body mass, estimated to be hundreds of kilograms, requires substantial energy input, making a high-risk, sporadic hunting routine metabolically inefficient compared to a reliable plant diet.
