Earthworms

It depends on what type of worm, some have a circualtory system and some do not.

it eats it through its mouth and poops it out its butt. easy.

I think it probably has to do with drying out- they move away from light to retain their moisture. We all know the sun dries things and since they live underground, they would be more susceptible to drying out and dying than other organisms.

Decomposer, it breaks down dead matter and turns it into soil.

ther are over 9,000 types of worms in the world :)

Circular muscles help in extension and narrowing of the body of the earthworm. When circular muscles contract the protractor muscles relax causing the retractor muscles to contract, thus withdrawing the setae.

Different worms have different defence mechanisms. Some are toxic, whereas others have sharp spines (bristles) that stick into and cause pain in potential attackers.

It differs from 1mm to over 30mm

bilateral symmetry- body plan in which an animal that can be dinided into 2 equal sdes.

this is supper gay hahahaha

Well the setae is what allows earthworms to move thorugh the dirt and stuff :)

Cold blooded.

As earthworms feed, they normally move through the soil and make small spaces. The spaces created by earthworms in the soil make aeration successful and thus enrich the soil with important nutrients.

No, worms by definition do not have skeletons. Some have coelom, a cavity in the body that supports certain higher movement functions.

All animals are consumers - only plants and some protists are producers.

in the earth- that's why they're called EARTHworms

catches insects and and does respiration.

No. Only spiders are arachnids.

The worms do make holes but it is to but oxygen in to decompose the soil and therefore making compost, they also drag leafs into the compost to eat and to make more soil well theirs your answer :).

I am pretty sure they have simple but very complex digestive systems

Earthworms don't have eyes. They blindly crawl around in the dirt.
0.An earthworm does not have eyes.

Yes, earthworms are coelomates because they have the "tube within a tube" body plan that characterises coelomates. More specifically, coelomates have a body cavity that is completely lined with cells derrived from the mesoderm (the germ layer of tissue found between the endoderm and ectoderm in embryonic development).

A pharynx in a worm is basically an organ that a worm uses to eat. It is thread-like I believe, and a worm pushes it out of their mouth, gets the food, and eats it. So I guess, it could be comparable to a tongue in a human.

Define "worm". If you mean earthworms, which are in Phylum Annelida, then the answer is a resounding "yes!". Earthworms decompose organic matter by eating decaying plants, and their feces (called "castings" in polite earthworm circles) is one of the best fertilizers in the world.

Earthworms also improve the soil by their digging and tunneling. Their movement turns over the soil, mixing nutrients . Their tunnels help water soak in and air get in too.

Other kinds of worms are not so good. Certain nematodes, which are smooth and frequently microscopic, can damage the roots of plants. Farmers spend lots of money trying to control this type of worm.
