Worms break down dead plants and animals into a simple

form that plants can use. They are decomposers so they break

apart these things into something simple the plants can use









Leaves decompose into castings

thanks to worms.

Just like you or me, worms can

drown in water. With too much

water, they cannot get the oxygen

that they need to live.

Worms do not have lungs like humans. Instead

they need to breath through their skin. In order for

this to happen they need to have a layer of moist

water on their skin… but not too much.

Too much water and they will drown in it.

Baby worms aren't born; they hatch from

a cocoon no bigger than a grain of rice.

A worm moves by expanding his body, clamping down

with the worm’s setae(hairs) and contracting to pull

itself forward. It will change where it clamps and

expand again. By alternating contracting and

expanding movement is achieved

Yes, there is a difference between the head and

the tail of a worm. Although it’s hard for us to

tell, worms definitely will move in a specific

direction.

Instead worms have an organ

called a gizzard to break down

food. Rocks, dirt and other

materials are mixed together to

break down the food by grinding.





The breaks down the food, much

like a blender breaks down food.

Yes… Somewhat.



Yes, but only the front or head end of the earthworm will survive and the amputated tail

portion will die.





This remaining front portion must also be long enough to contain the clitellum and at

least 10 segments behind the clitellum. This makes up about half the length of the worm.

Some species of worms can have over 100

segments. They likely would not have many

more than that however

Most worms will avoid the daylight

because they could dry out and not be

able to breath.





Worms do not have eyes, but they can

sense light. If they're in light too long

they'll become paralyzed.

Earthworms are amazingly strong. They can

easily shift stones 60 times their own weight!
