Why are segmented worms important?

Answer 1

The segmentation in worms is an advantage because it is helpful in the locomotion or movement of a worm. Each segment has many muscles in it and when those are flexed they push against the rest of the body to propel it forward. Without body segments the worms would not be able to move.

Answer 2

Worms naturally move through the soil and in doing so, they soften it a little which encourages crops to grow. Without the worms, the soil would be hard, so the farmer would have greater difficulty ploughing it, the plants would then struggle to get roots out, and then water would also be slower to infiltrate.

Other than agricultural uses, I can't think of any other way in which they are helpful, although there are probably more.

Answer 3

They're good for fishing earthworms, and many other descriptions.

Answer 4

because they help the ocean be clean.
