There are a number so named. They are called peats if the remains may be identified as partially decomposed or mucks which consist of well-decomposed, finely divided organic remains. Another name for mucks is humus.
biomass
Mixture of eroded rock and decomposed organic matter.
Humus
dirt
I believe it's called humus. It's decomposed plants and in some cases animals.
Topsoil has more organic matter in it than the rest of the soil. Decomposed organic matter (humus) is usually dark brown or black.
Basically, fallen leaves and partially decomposed organic matter...if we're talking science, that is.
germination is low because microbes are active in decomposing the soil
Compost is partially decomposed organic matter. Organic matter increases the soil's water holding capacity, increases fertility and its ability to hold nutrients
easily decomposed OM
Mixture of eroded rock and decomposed organic matter.
Humus
it is made of decomposed organic matter and and mineral content.
Soil contains partially decomposed organic matter that the earthworm extracts its food from and excrete the mineral parts of the soil as waste. This waste is mixed with the worms urine and becomes a very useful plant fertilizer compared to the original organic matter which may not even be accessible to the plants.
dirt
Organic matter from kitchen and yards that decompose would be leaves, twigs, fruit, food, and eggshells. These can all be decomposed.
They eat dead organic matter.Decomposers eat dead animals and plant matter.
