View full question & answer→Characteristics of local earthworms:
(1) Local earthworms eat soll.
(2) If the local earthworms do not find food, they do not move elsewhere, but remain dormant inside the soil.
(3) Earthworms continuous its activities underground even at high temperature in the deserts of Rajasthan or at low temperature on the top of the Himalayas.
→ Local earthworms go deep into the soil. During the life span of 15 years they keep on making day and night endless billions of holes inside the soil. They dig a hole, come up from another hole, when they come on the surface of the soil they leave a mineral-rich waste. (Hagaar).
This makes the soil porous.
→As the local earthworms moves up and down, it secretes enzymes from its body and forms a lining on the inside of these, so these holes resist external pressure. Due to which the rain- water easily seeps into the ground and raises the ground water level and stops soil erosion.
→ When earthworms enter the soil, they eat soil, sand, raw stone (loose or soft rock material), lime, etc. and reach up to the soft soil inside. destroying disease-causing pathogens in the soil in their intestine. It swallows beneficial organisms and strengthens them and releases them to the soil through excreta.
