A phylum has more biodiversity because class is what narrows the phyla down even more. ( The order of largest biodiversity to smallest biodiversity is domain, kingdom, phylum, class, order, genus, species)
The phylum would have more number of species as compared to that of class. This is because according to classification phylum is bigger than class.
