Question

today, you will observe four types of invertebrates: earthworms, mealworms, crickets and crayfish. at the end, you will compare these invertebrates with some familiar vertebrates. this chart shows the classification of these animals. (some information has been omitted to keep things simple.)

1. all vertebrates are in the phylum _______________.

are all invertebrates in the same phylum?
how do you know?

Explanation:

Looking at the chart, vertebrates (Dog, Cat, Human) are under the phylum Chordata. For invertebrates, Earthworm is in Annelida phylum and Mealworm, Cricket, Crayfish are in Arthropoda phylum. So they are not in the same phylum as there are different phylum names for different invertebrates in the chart.

Answer:

All vertebrates are in the phylum Chordata. No, all invertebrates are not in the same phylum. Earthworm is in Annelida and Mealworm, Cricket, Crayfish are in Arthropoda (as per the chart).
