Which category includes falcons?

Which category includes falcons?

• A. Invertebrate
• B. Fish
• C. Mammal
• D. Vertebrate

Answer: (D)

The main idea is identifying animals by having a backbone. Falcons are vertebrates because they have a backbone in their internal skeleton. Birds, including falcons, belong to the vertebrate group, which also includes fish, mammals, and reptiles. They are not invertebrates, since those animals lack a backbone, and they aren’t fish or mammals—their features include feathers and laying eggs, not scales or fur with mammary milk. So, falcons belong in the Vertebrate category.
