through their skin
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)
Waste is removed through a designated opening
Unused food material as waste.
Solid waste is eliminated through the anus.
"Human Waste"is eliminated through the sweat, urine , feces and respiration
dirt
they dispose waste of the earthworms.
worms eat through the soil then it removes its waste
The body cannot use everything that is in food. What is not used becomes waste. The waste must be eliminated or it can be toxic to the body.
waste created by cellular metabolism is eliminated by the nephridia.
The intestines help carry the earthworm's waste to the anus, where it is expelled from the worm.
Soil contains partially decomposed organic matter that the earthworm extracts its food from and excrete the mineral parts of the soil as waste. This waste is mixed with the worms urine and becomes a very useful plant fertilizer compared to the original organic matter which may not even be accessible to the plants.
