No, earthworms aren't arthropods; earthworms, along with leeches and ragworms belong to phylum Annelida which is a different phylum from Arthropoda (the arthropods). Arthropods are characterized by jointed limbs, segmented bodies, and a hard exoskeleton; which description better suits insects, millipedes, crustaceans, etc.
Interestingly enough, there is a worm called a velvet worm which is thought to be related to arthropods.
Earthworms decompose dead organisms
No they are not. They do not have 6 legs. They are part of a phylum called Annelida. In that phylum they are in a class called Clitellata. In contrast, insects are part or the phylum Arthropoda and the class Insecta,
Annelids are segmented in much the same way as arthropods (think of earthworms). Primitive arthropods include centi- and millipedes, with many unspecialized legs (legs in more advanced arthropods often specialized to form antennae, mandibles and pedipalps), and they're as long and thin as segmented worms. Also, there's a possible 'intermediate form', Peripatus, the velvet worm, being long, thin and soft-skinned, but also having many stubby legs!
earthworms travel faster
The bacteria in earthworms is called Eisenia Fetida it's in most earthworms
an open circulatory system
No they aren't, they sometimes attack earthworms, ants, snails, shellfish and many other arthropods.

It belongs to the phylum Platyhelminthes.
Flatwood salamanders are an endangered animal. They eat mostly arthropods and earthworms. They are carnivorous animals and will not eat any plants.

No. Millipedes are myriapods, meaning "many feet". Centipedes are also myriapods. Segmented worms are annelids; earthworms and leaches belong to this group. Also, myriapods are arthropods; annelids are not.
Yes it is. Badgers have a wide variety of foods in their diet. They will eat earthworms, arthropods, mammals, birds, reptiles and even fish. They also eat cereals, fruits and seeds.

They express the characteristics inherent to arthropods. All insects are arthropods. Not all arthropods are insects.
NO Mammals are not arthropods. Arthropods are insects.
arthropods are eukaryotic because arthropods are animals.
