what 2 organisms belong to the same phylum

Answer 1

I am not sure what your answer choices are but:

Phylum is a pretty broad classification, just under kingdom. If we pick a phylum, lets say Cnidaria. Some organisms from you phylum you probably will recognize are jellyfish. Jellyfish also share this phylum with corals.

Another example could come from the phylum Chordata. Homo sapiens are from this phylum as well as any bird.

Phylum is a very broad classification of organisms so there are a massive number of answers. I hope this helps.
