Chordata is to Animalia as phylum is to:
Kingdom
Chordata is a phylum within the Animalia kingdom. So, the equivalent term in the Animalia kingdom would also be a phylum.
To find the answer to this question, we need to understand the relationship between the terms "Chordata" and "Animalia," and then apply the same relationship to find the term that is analogous to "phylum."
"Chordata" is a subphylum within the phylum "Animalia." In taxonomy, "Animalia" refers to the kingdom that includes all animals. Within the kingdom "Animalia," organisms are further classified into different phyla based on shared characteristics. "Chordata" is one of the many phyla within the animal kingdom.
Applying the same relationship, we can conclude that "phylum" is the broader category, and we need to find a term that represents a more specific subcategory within a broader category.
The term that represents a more specific subcategory within a broader category is "class." In taxonomy, "phylum" is the higher level, while "class" is the next level of classification below it, where organisms are further categorized based on additional shared characteristics.
Therefore, the answer is: "Class."
