Okay so what would be next?

Answer : Lungs and four limbs are necessary because lungs make oxygen fro air to help the organism breathe and the four limbs help the organism navigate the land, move away from predator , and catch food.
had to put those 4 together :)
Thank you so much!(: Could you help me with another question please?

How are chordates and vertebrates related?
They lack true bones, but there is more to it I believe hold on
all chordates have: a postanal tail, notochord, pharyngeal pouches, and nerve cord
And that's it?
yep that should be it . vetebrates have extra stuff , but that would state the differences, you want how they are related. Also all vetebrates are chordates (to a point)
