Sure, here is a possible 3 level inheritance hierarchy for living things on Earth:
Level 1: Domain
Eukarya
Level 2: Kingdom
Animalia
Level 3: Phylum
Chordata
This hierarchy starts with the highest level of classification, which is the Domain level, and narrows down to the specific group of organisms in question, which in this case are animals with a backbone (Chordata). This 3-level hierarchy could be further subdivided into more specific categories, such as classes, orders, families, genera, and species, depending on the level of detail needed.
