please mark me as the brainliest answer
Explanation:
1) All earthworms are not used for vermicompost. Earthworms are classified as humus formers and humus feeders. Among which humus formers are good for vermicompost and they include Eudrilus eugenics, Eisenia fetidae, Perionyx excavators. Pheretima posthuma is not recommended for vermicomposting as it is a humus feeder.
2) Vermicomposting (vermis from the Latin for worm) is a mesophilic process [20] which involves a joint action of earthworms (active at 10–32°C) and mesophilic microbes [21] for the conversion of organic wastes into a valuable end product known as vermicompost
3) Pollution from animal excreta and organic waste from kitchen can be most profitable minimized using them in the generation of biogas. Biogas is a mixture of methane and carbon dioxide resulting from the anaerobic decomposition of such waste materials as domestic, industrial and agricultural sewage.
4) The only method of forcing mush- room mycelia to change from the vegetative phase to a reproductive state is to apply a cover of a suitable material—called the casing layer—on the surface of the spawned compost.
5) So the correct answer is 'Coelomic fluid'.
6) Vermicomposting, or worm composting, is the top option for food waste recycling (and alternative to hot composting) in your apartment or flat, as you employ a particular species of earthworm to consume decomposing food scraps, paper, and other organic-based household waste.
7) Vermicompost (vermi-compost) is the product of the decomposition process using various species of worms, usually red wigglers, white worms, and other earthworms, to create a mixture of decomposing vegetable or food waste, bedding materials, and vermicast. ... Vermicomposting can also be applied for treatment of sewage.
8) Can Any Type of Earthworm be Used for Vermicomposting? The best types of worms for vermicomposting are red wigglers (Eisenia fetida) and redworms (Lumbricus rubellus). These two species make great worms for the compost bin because they prefer a compost environment to plain soil, and they are very easy to keep.
9) Typhlosoles occur in bivalve mollusks, lampreys and some annelids and echinoderms. In earthworms, it is a dorsal flap of the intestine that runs along most of its length, effectively forming a tube within a tube, and increasing the absorption area by that of its inner surface.
10) The vermicompost contains high concentration of organic material, silt, clay and is rich in many soil nutrients such as nitrogen, sulphur, potash, phosphorus, calcium, magnesium, etc. In soil, much of the phosphorus is bound in organic matter in a form that is not available to plants.
