What does the decomposition of organic matter by heat describe?
Pyrolysis
Is it true or False that Fossil Fuels are liquid deposits of iron ore found only in sedimentary rock formations?
FALSE. Fossil fuels come from organic matter that has undergone anaerobic decomposition. We suspect that much of our fossil fuel comes from buried plankton and dinosaurs.
What is organic deposition?
Any thing that is organic and dies
Formation of manure from leaves is a physical change?
Farmyard manure creates heat energy from decomposition of leaves. There is also physical change because the leaves' structure is broken down. The main factors for producing good manure are: water, which is already part of the manure; heat, which is generated by the decomposing leaves; and air, which is needed to aid the decomposition, because decomposition is a very slow form of "burning". Quite a high temperature can be generated in a manure heap or a compost heap.
Why do you have to remove the organic matter in a soil hydrometer test?
Inaccuracy in the particle size and therefore in soil characterization, classification and texture is the reason for why organic matter has to be removed in soil hydrometer tests. Samples may contain carbonates, organic matter, oxides and soluble salts. All four of the above-mentioned soil constituents need to be removed since they bind soil particles into bigger sizes.
What does the decomposition of organic matter by heat describe?
Pyrolysis
Dead organic matter is prevented from accumulating by the cycle of?
decomposition
What is dry decomposition?
Decomposition (or rotting) is the process by which organic substances are broken down into simpler forms of matter.
What are the factors affecting organic matter decomposition?
TEMPERATURE MOISTURE AIR
What matter is converted into animal and microbial tissue during decomposition?
Organic matter is converted into animal and microbial tissue during decomposition. This matter can be then used to fertilize the soil.
Why good air flow is necessary for the decomposition of the organic matter?
Good air flow is necessary for the decomposition of organic matter because decaying matter builds up gases. If the gases are not allowed to escape the area, there could be an explosion.
What is added to the atmosphere during bacterial decomposition of organic matter?
bacteria or fungi
How does sterile soil prevent decomposition?
There are no microbes present to break down organic matter
Fuel formed under the earths surface by the decomposition of organic matter is called?
a boat
What is Eutrification?
The process in which oxygen is removed from the water by the decomposition of large amounts of organic matter
What is humus a source of?
Carbon is what humus is a source of.Specifically, the term designates organic matter in soil. The organic matter is created by the decomposition of animal and plant matter. Decomposition results in increased availability of carbon. Humus also will attract ammonium, copper, magnesium, potassium and zinc.
What breaks organic matter?
Living organisms break down organic matter. The matter can be animal or plant in origin even though it always will be carbon-based. The breakdown may be through fermentation in anaerobic decomposition or oxidation through aerobic decomposition, or respectively without or with the presence of oxygen.
