    Answer:

Living things are classified into Kingdoms, two of which are the Plant Kingdom and the Animal Kingdom. Animals are grouped according to characteristics they have in common and separated on the basis of their differences. Zoologists (who study animals) use a classification system that divides the Animal Kingdom into smaller groups, called Phyla, based on similarities. Each phylum is divided further into Classes. These groups continue to be divided into smaller and smaller sections until only one animal, the species, is left by itself.

Animal Kingdom is classified into two major different groups, Vertebrates and Invertebrates. Vertebrates are animals that have a backbone. Invertebrates don't have backbones. In reality, there are actually many more phyla than these two and even some smaller groups called subphyla.
