Explanation:

By their activity in the soil, earthworms offer many benefits: increased nutrient availability, better drainage, and a more stable soil structure, all of which help improve farm productivity. Worms feed on plant debris (dead roots, leaves, grasses, manure) and soil. Nitrogen in the casts is readily available to plants. Earthworms are decomposers. They decompose the organic matter and convert the complex substances into simpler digested molecules. These molecules are released into the soil by the feces of earthworms. This way earthworms replenish the soil fertility and return the nutrients back to the ecosystem
