No, they do not.
Most Annelids live in the soil. They eat food which is available in the soil. Examples of Annelids are earthworms.
Annelids are earthworms or soil worms :)
Annelids are found worldwide in moist or wet environments ranging from marine habitats to moist soil.
Annelids are helpful in that they burrow in the soil and these burroughs connect to the surface and admit air into the soil (aeration. This also allows water to percolate or pass down into the soil with the aid of gravity. The digestive waste and soil (ingested when feeding) will be deposited on the soil surface thus bringing minerals to the surface to benefit plants.
Earthworms, of the phylum Annelida are food for birds, and keep the soil aerated. Sometimes large earthworms are used for dissection in first-term Biology classes, to teach the understanding of basic internal organs. Leeches are also annelids, and help with healing wounds. Yes, leeches are back in the medical field!
The most important function of annelids, or earth worms, to their ecological environment is to turn over the soil, making it healthier for plant life. This is accomplished both by their burrowing habits and through eating and excreting dirt.
A sunflower needs water, hot weather, sunlight, air, soil, nutrients and oxygen to create its food.
Soil that contains oxygen is known as oxic soil. On other hand soil which lacks the oxygen is known as anoxic soil
well don't you need water and oxygen? so why not soil. soil feeds plants and grass, which needs water and oxygen.
