An earthworm's lack of appendages is an adaptation that enhances its ability to burrow through soil. The streamlined, elongated body allows it to move efficiently through tight spaces, reducing resistance as it pushes through the earth. This body shape also minimizes the chance of getting snagged on obstacles in the soil, enabling the worm to navigate its environment effectively while aerating the soil and facilitating nutrient cycling.
Earthworms lack appendages to prevent getting stuck in burrows, as they move by elongating and contracting their bodies. This streamlined form allows them to navigate through soil easily. Additionally, not having appendages reduces surface area, helping them move efficiently through their burrowing activities.
lala that's what I think
An earthworm's lack of appendages helps reduce drag as it moves through the soil, making burrowing more efficient. The worm's cylindrical shape also allows it to move easily through tight spaces underground. Additionally, the lack of appendages minimizes the risk of getting stuck in narrow tunnels.
Dead plants and animals would pile up if it were not for the earthworms.
If it is a rainy day some might show up. You can buy earthworms too.

this is tricky and earthworms might sing you will never know I'm not a sciences tip of person so sorry ( but i don't think they could sing

Due to the rigidity of the arthropod exoskeleton, the safest answer might be "jointed' ones - hence the phylum's name Arthropoda, from the Greek, meaning, jointed appendages. They do evidence a variety of appendages: legs, pincers, wings, swimmerets, antennae, tails, etc., depending on what environment and food source they are adapted to.

Earthworms might look smooth but they have bristles, called setae, that help to hold them in their tunnels.
