What is rotting vegetation?
Rotting vegetation refers to plant material that has begun to decay and break down over time. This process is part of natural decomposition, where microorganisms like bacteria and fungi break down the organic matter, returning nutrients to the soil. Rotting vegetation contributes to the nutrient cycle in ecosystems.
Can a virus decompose organic material?
Viruses cannot decompose organic material on their own because they lack the cellular machinery to carry out metabolic processes. However, viruses can indirectly contribute to the decomposition of organic material by infecting and killing host organisms, which then become part of the decomposition process by bacteria and fungi.
How does organic matter forms when once living material undergoes?
When living material undergoes decomposition, organic matter forms as the organic compounds within the material break down into simpler molecules. This process is driven by the activity of decomposers such as bacteria, fungi, and other organisms that break down complex organic compounds into humus, which is a key component of organic matter in soil.
Is hair organic?
Yes, hair is made of organic material. It mainly consists of a protein called keratin, which is an organic compound.
Can organic material be made by nonliving things?
Yes. Given the proper mixtures of carbon dioxide, water, ammonia, etc., you can add heat or an electric spark (energy), and get stable organic molecules, such as amino acids quite easily. Such is an example of the creation of organic material through nonliving means.
A mixture of small mineral fragments and organic matter?
Soil
What is a mixture of small mineral fragments and organic matter?
SOIL
Soil is a mixture of weathered rock mineral fragments water air and?
organic matter, such as decomposed plant material and microorganisms. These components interact to provide nutrients and support plant growth.
Is a mixture of weathered rock mineral fragments water air and decayed organic matter?
soil
What material is primarily a mixture of weathered rock and organic material?
soil
Are Sedimentary rocks formed from broken fragments called organic?
No, sedimentary rocks formed from broken fragments are called clastic sedimentary rocks. Organic sedimentary rocks are formed from the accumulation of organic material such as plant debris or remains of marine organisms.
Is soil substance or mixture?
Soil is considered a mixture because it is composed of various materials such as minerals, organic matter, water, and air. It is not a pure substance because it consists of different components that are physically combined rather than chemically bonded.
What are the 4 main layers of soil?
Organic Layer - plant litter Surface Layer - mineral and organic mixture Subsoil - contains clay, iron, aluminium Substratum - parent material
Which soil type is richest in organic material?
Loam, which is a mixture of clay, sand & humus.
Soil types is richest in organic material?
Loam, which is a mixture of clay, sand & humus.
Is soil an compound element or mixture?
Soil is a mixture which is made up of a number of elements and compounds. Some of the components of soil include mineral fragments, decayed organic matter, water and air.
Is soil a compound mixture element?
Soil is not a compound, mixture, or element—it is a complex combination of minerals, organic matter, water, and air. It is a mixture made up of various components such as sand, silt, clay, organic material, and microorganisms.
