yes, this is true
Earthworms obtain their food from the organic material found in soil. This means that they are more likely to be found in soils with high organic content.

When soil is labeled as "rich", it means it has plenty of organic material which provides the nutrients to support healthy plant growth. Plants don't do well in poor soil - nutrients must be added to it if they are to thrive.
Organically rich soils are formed from organic material. Readily found examples of organic matter that's found on and near the surface of the soil are the breakdown of yard waste such as leaf litter; and the death and decomposition of the critters of the soil food web. Such critters include beetles, earthworms, and microarthropods.
That would be "compost"or "humus".
yes, this is true
A dark brown, fresh smelling, nutrient rich organic material called humus is what organic garbage turns into after it's composted.
A black shale is a form of dark muddy rock, which is rich in sulphides and organic material.
They break down a lot of fresh organic material into compost, or rich soil.
They are similar because the everglades are rich with nutrients of all sources, like our kidneys they store everything.

The O horizon contains the most organic matter in a soil profile. It is the top layer of organic material such as decaying leaves, branches, and other plant debris that is actively decomposing. The A horizon, also known as the topsoil, is a layer rich in minerals and organic matter that is developed from the decomposition of plant material in the O horizon.
Desert soils contain a high percentage of sand and are low in organic material. This happens in areas where there are few plants that would provide the decayed leaves and other dead organic material called humus. Humus is rich in nutrients and is better able to hold water than sand.
Mitochondria use rich organic compounds, glucose, to produce ATP.
