Detailed explanation-2: -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.

Detailed explanation-3: -The food is stored in the crop and then ground up into small digestible pieces in the gizzard. Earthworms need a gizzard because they do not have any teeth. The body absorbs nutrients through the small intestine.

Detailed explanation-4: -They’re high in protein and have high levels of iron and of amino acids, which help break down food and repair body tissue. They also contain copper, manganese and zinc. Earthworms are a source of calcium as well-on a par with the amount in fresh cheese or cow’s milk, says Dufour.

Detailed explanation-5: -Eggshells. A Worm can eat eggshells, which provide calcium and grit to break down other foods. Paper. Paper and cardboard is also a rich source of carbon when feeding worms. Cotton. Fruit and vegetable waste. Coffee grounds. Animal Manures. Leaves. Acidic food. More items •11-Feb-2022
