Final answer:
Sauropods had several adaptations related to their large size, including efficient digestion, hollow bones, and pneumaticity. These adaptations allowed them to support their massive bodies and sustain a herbivorous lifestyle.
Step-by-step explanation:
- Efficient digestion: Sauropods had long necks and a unique digestive system that allowed them to process large amounts of vegetation. They had long, narrow skulls and multiple sets of teeth to efficiently break down plant material.
- Hollow bones: Sauropods had hollow bones, similar to modern birds, which made them lightweight despite their large size. This adaptation helped them support their massive bodies while minimizing energy expenditure.
- Pneumaticity: Sauropods had air sacs within their bodies that connected to their vertebrae. This unique feature helped to lighten their bones even further and potentially aid in respiration.
