Because, they swallow the soil to make it fertile.
Earthworms are an important part of the soil environment, and the growth of plants. Oil is deadly to earthworms.
Yes, soil is essential for earthworms as they burrow through it to create tunnels and extract nutrients. Earthworms rely on soil for food, shelter, and protection. Without soil, earthworms would struggle to survive.
Because earthworms eat just about every other organism in the soil.
they fertilize the soil
Earthworms cling to soil using their setae, which are tiny bristles located on their body. These setae help the earthworms move through the soil by gripping and anchoring onto the soil particles. This allows the earthworms to burrow efficiently and navigate through their environment.
Earthworms help to aerate the soil when they burrow, creating channels for air and water to penetrate into the soil. Their movement also helps to mix organic matter into the soil, which improves soil structure and fertility. Furthermore, earthworms break down organic matter, producing nutrient-rich castings that enrich the soil for plant growth.
The answer is that earthworms help to build soil and fertilize
Earthworms play a vital role in maintaining soil health by breaking down organic matter, aerating the soil, and improving soil structure. This enhances nutrient cycling and promotes plant growth, making earthworms essential for healthy ecosystems and sustainable agriculture.
Earthworms require oxygen to breathe, and when soil is saturated with water, there is not enough air present for the earthworms to survive. The excess water limits the movement of air in the soil, causing oxygen levels to drop and suffocating the earthworms.
Earthworms help decompose organic matter in compost heaps and in the soil.
If all the earthworms disappeared from a lawn, more earthworms would come in. But, if your question is that what would happen if earthworms would no longer live in a lawn, then the lawn would become less fertile, because earthworms keep the soil good.
