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.
This means that many many different classes can come under phylum but a phyla cannot come under class.
So, the phylum has diversity of organism in it. At hierarchical level the organism belonging to phylum are at higher level and organism belonging to class are at lower levels.
