Species A and species B are in the same phylum. Species A and species C, but not species B, are in the same order. From this information you can conclude that .

Species A, B and C are in the same phylum

Explanation:

Organisms are grouped according to a taxonomic hierarchy into a taxonomic rank. Taxonomic ranks include species, genus, order, family etc.

Each taxonomic rank has a hierarchy (as given below)

Domain

Kingdom

Phylum

Class

Order

Family

Genus

Specie

The Specie is the lowest rank and the Domain is the highest. All organisms that belong to a lower rank belong to the same upper rank. For instance, all organisms that belong to the same species belong to the same genus, however, not all organisms that belong to the same genus belong to the same specie.

So in this question, since species A and C are in the same order, that means they are in the same class, phylum...

Also species A and B are in the same phylum, since species C is in the same phylum as A also, it mean all three species are in the same phylum.

the reason the two sea urchins don't compete with each other for food, resources, etc. is because the urchins have adapted to the environment but they have also adapted to each other. this is most likely because the genes of the sea urchins.
