Find out the role and significance of the worm.

The worm (if we mean an earthworm) plays an important role in the life of the Earth. He destroys and digests the excrement and corpses of animals that rest in the ground, thereby freeing the earth from them. Also, the excrement of the worm is an excellent fertilizer, thanks to which the soil receives the necessary elements and becomes more fertile. And finally, due to their vital activity (they live underground), they dig small passages, passages in it, this increases the looseness of the soil, which contributes to the accelerated growth of the root system in plants, and also increases the amount of oxygen in the earth, which contributes to an increase in the number of other living organisms in the soil, such as bacteria that decompose the rotten remains of animals and plants.
