No skeleton, it may look like it but there isn't one. Because when you squish the worm there is nothing but flesh and blood.  However there is a certain type of worm that has a skeleton just not an earthworm. (I don't know what the name is of the worm that has a skeleton.)
Hope this helps:)

A work has no skeleton, which is why it can bend in all different directions, but the main reason i know this, is cause if you pinch a work between your thumb and forefinger, it will break, and there is nothing on the inside of the worm that indicates there is a skeleton

How are the plants in a desert ecosystem most likely to differ from the plants in a rain forest ecosystem?
erik [133]
Hey,

I believe this answer is A: The desert plants are likely to be better at retaining water.

Which they do, and they have to cause water is very scarce in the desert unlike the rain forest.

Desert plants likely to be larger is not proven and most plants can vary in size.

Narrower stems may have something to do with it but that goes back to they have to hold more water so this is incorrect.

Brighter flowers doesn't have anything to do with water consumption within a plant so this is incorrect as well.

Hope this helps!
