Earthworms

Cephalization is the concentration of nerve cells at one end of the body. All of an earthworms sensory organs, including the nerve cells are in one part of the body. This can be proven through dissection.

Yes, in a sense. These tunnels arent all well structered and can easily colapse on them selves. But the answer is still yes.

earthworms move by it body shape when earthworms extension of body rear part Rolex the backer part of body then they move forward

The collective noun for worms is either a knot or a Bryce.

They don not like sun at all, it will dry them out.

The fact that it is not a plant, so its not a plantae, it is too big Tobe a bacterium, so is it not an archea ether. These are the only relatively close kindoms that an earthworm could be categorized.

the aortic arches carry blood from the dorsal blood vessel to the ventral blood vessel

• On the outside: the setae (or tiny hairlike structures that help them move) and the mouth.
• On the inside: the brain, esophagus, crop, gizzard, intestine, 5 pairs of hearts, the nerve cord, and blood vessels.

All worms have both male reproductive organs and female reproductive organs. This means that they are hermaphrodites. The female organs of a worm include the egg sacs and ovaries. The male organs are two pairs of testes, three pairs of seminal vesicles and sperm funnels. Despite the fact that worms have both male and female organs; it must mate with another worm in order to reproduce its own kind.

The worms help the soil, thus helping plants. They eat food that you throw out, and their body waste helps the soil. They break down minerals into forms that are more easily used by plants. Small burrowing animals sometimes eat things that might damage plant roots, which helps plants too. This affects us because it makes our food from the plants healthier.

Earthworms do not shed their skin. Earthworms are not snakes and their skin actually grows as they grow larger. Earthworms do shed bits of waste material.

OK so my friend thinks this nugget is a stupid question, but i don't nugget, and its got me thinking. Earthworms are pretty much "all nugget" i guess, but then again, their bodies have five sets of nuggets, and they can go around either way. So, I'I'm not sure myself. You can lick a nugget.

Usually the head of the worm will survive and grow back a tail, while the tail part dies when all energy are used up. In some cases it may also grow back into another worm.

Did you get into environmental studies also?

I did and I'm not sure so im going to say perfume :0

the same way any other organism does; it is consumed and therefore recycled by other decomposers when it dies. Earthworms are considered decomposers because they eat rotting or dead organisms and they essentially excrete the chemical nutrients that enrich soil so that plants can grow.

I think it is about 70 - 80 percent but this answer may not be accurate.

Earthworms belong to the Phylum Annelida and particularly the genus Lumbricus. The Phylum is characterised by body segmentation and a body cavity called acoelom. It includes marine worms, leaches and earthworms.

It holds the male and female reproductive organs.

Naturally human bodies are much more complex than those of worms. For instance, humans have skeletal system, while worms are invertebrates. They also have a very weak nervous system which doesn't allow them to feel any pain. Humans generally have good senses we can taste, touch, hear, smell, and see well (we can also feel pain). Worms only have eye spots which give them awareness on the level of light in their environment however don't actually give them vision. Worms have two main blood vessels: a dorsal and a ventral vessel. These vessels circulate blood from the head to the tail of their bodies. The blood is moved from waves of contraction in the vessel. Both humans and worms are alike in that they both have what is referred to as a 'closed circulatory system'. However in our system we have only one heart and the two fluids we transport are blood and lymph; meanwhile worms have 5 hearts which circulate blood.

In a worms excretory system basically food goes in the mouth and comes out the opposite end. of an earthworm is very simple. In short, food goes in one end and comes out the other. Niphridia helps to absorb some water during the process. They are found in pairs in every segment except the first 3 and the last one. Niphridia are to worms what kidney's are to humans.

[1] Earthworms can make plants grow better, and possibly faster, by the improvements that they make to soil. They tunnel through soil, thereby opening up passageways for air, nutrients, and water. [2] They open up pore spaces for the passing of water, thereby improving waterholding and drainage in soil. [3] They eat and eliminate, thereby building up organic matter in soil. [4] They die and decay, thereby adding their body and body parts to the organic content of soil.

put a worm on a rock and cover it with a leaf

Ants will eat any living (or dead) thing they can bring into their colony even if they have to rip it apart alive. I've seen it.

yes earthworms have babies. Earthworms carry both male and female reproductive parts --they are hermaphroditic. Two worms line up side to side with their heads at opposite ends. Huge amounts of mucus secrete from the worms, passing the male sperm from one to the other. When the worm is alone it then secretes another mucus ring which slides over the worms body in which the eggs cling onto which then fertilizes them. Then the eggs slip off the worm's body and is left in a cocoon with is left in the soil.

moisture in the soil that they live in that's how they barrow
