Which term describes animals that do not have backbones?

Explanation:
Animals without backbones are called invertebrates. This group includes insects, spiders, worms, and mollusks. Animals with backbones are vertebrates, such as fish, birds, mammals, reptiles, and amphibians. The other terms don’t describe animals: a dam is a female parent in animal breeding, and an atom is a basic unit of matter, not an animal.
