Hi what is the domain kingdom and class for worm, plant, grasshopper, frog, turtle, snail, spider and turtle, fern

I can only tell you the kingdom,because some of those split at the class level, meaning some are in one, and the rest in another etc. All the above except the fern are in the animal kingdom. If you want the class, then you need more detail on them first. And worms are separated at the phylum (which comes between kingdom and class). You need some more info please
