Cut it open or observe it.

You look at its crop or the worm's scat.
Earthworms do not actually eat soil; they consume the organic matter within the soil as they burrow through it. This organic matter includes decomposing plant material, bacteria, and fungi. By observing an earthworm's behavior and the presence of organic matter in its digestive system, one can determine that they do not consume soil directly.
You can find out if an earthworm eats soil by observing it in a controlled environment, such as a terrarium, with soil and other food sources. If you see the earthworm consuming soil by ingesting it and passing it through its digestive system, then it is likely consuming the soil. Additionally, the presence of soil particles or organic matter in the earthworm's waste (castings) can indicate that it is eating soil.
by dissecting the earthworm and looking inside of the stomach...
An earthworm is an omnivore (but more specifically a detritivore as they mainly eat decaying plant matter). It eats whatever material (plant or animal) that it ingests from the soil.
The way that the earthworm <annelida> adapts to filtering food out of the soil is that it separates the waste and the food. It then eats the food and releases the waste! (ewwwwww)
No, an earthworm cannot produce food because it comes in Kingdom Animalia which includes organisms who are heterotrophs and are not capable of producing food for themselves. instead they depend on other autotrophs for nutrition. the earthworm eats dead organic matter from the soil.

Earthworms eat organic matter found in soil such as decomposing leaves, plant roots, and microorganisms. They ingest soil along with the organic matter and extract nutrients from it as they digest. You can observe earthworms in a controlled environment with soil and organic material to see if they consume the soil particles.
An earthworm, while moving, chews up some soil and spits out the same amount of soil back into the ground. The soil which was eaten becomes fertile and more plants will grow on fertile soil. therefore, an earthworm helps a farmer by making soil fertile.
