What an important part of topsoil?
decayed organic matter
An important part of topsoil is?
decayed organic matter
Is it true that soil is made completely of decayed plant material?
No, it is not true. Naturally occurring soil is a mixture of non-organic particles (like clay, silt, sand and gravel), organic matter in all stages of decay, and living organisms (like bacteria, fungi and insect larvae). You can make soil that is entirely made from organic matter, but it will not consist only of decayed plant material. Even if you start with a pile of dead leaves, by the time it has become soil, it is no longer purely plant material. Decay (apart from mechanical erosion) is only possible through the action of decomposers living off the leaves, dying and eventually becoming part of the soil. The decomposers are fungi or animals, not plants. The organic matter in soil does not have to come from plants - dead pets work just fine! Then you get soil composed of decayed animal material, plus living and dead microorganisms, fungi and animals, without any plant material.
What is soil made of?
Soil is made up of a mixture of organic material and minerals. The organic matter comes from dead plants and many of the minerals come from the rocks underground. These rocks, which are part of the lithosphere, are referred to as bedrock. Because the plants grow on top of the soil and the rocks are found underground, soil is made up of layers.
Is phosphate organic or inorganic?
No, ATP is an organic compound. The full name is adenosine triphosphate, and the adenosine part is made of two carbon rings interlocked with each other. The three phosphate groups are inorganic, and when one is removed from the ATP molecule, the resulting phosphate group is typically notated as Pi, for inorganic phosphate.

What does organic mean sowhat would it mean for a rock to be considered an''organic rock''?
Organic means to be made with carbon. More importantly for geology it means to made either by or from the remains of a living thing. So to be an organic rock part of it's materials are made by or from life.
What part of soil is made up of the decayed remains of plants and animals?
Five
What are all the part of your body made from?
The human body is composed of living cells. Cells are composed of lipids, proteins and other organic materials.
Part of soil that includes decayed parts?
The O horizon is the top layer of soul. It contains living and decomposed materials from animals and plants. It is thin and dark.
What materials can carbon dating be used to date?
Carbon dating can be used to date organic materials that were once part of a living organism, such as wood, bone, charcoal, and plant remains. It is most commonly used on objects that are less than 50,000 years old.
A substance is organic if it did not arise from materials that were once part of a living thing true of false?
true
What ar chicken bones made out of?
Bone is made up of a matrix organic and inorganic materials, that harden to trap cells. The inorganic part (bone mineral) is called hydroxyapatite. The organic part contains collagens that are exported to form Fibrils and include other materials such as:- glycosaminoglycans, osteocalcin, osteonectin, bone sialo protein, osteopontin with a cell attachment factor. Calcium is used to help strengthen bones and the reformation of broken bones.
