What is a chemoautotroph
an organism that devries energy from the oxidation of inorganic compounds
|
There are two stages of aerobic respiration, the
transitions stage and the Krebs cycle
|
What is the first step of methanogenesis
hydrolysis and fermentation
|
The process by which a fossil is formed is called
fosilization
|
there are two types of combustion What are they called
complete and incomplete
|
the concentration of carbon dioxide in the air or water should always be lower or higher?
higher
|
During the transition stage, a product of glycolysis is converted into acetyl-CoA in the mitochondria. what is it called?
Pyruvate
|
Methane is oxidized to carbon dioxide and water in the atmosphere, what is the first step
hydroxyl radical reaction
|
When deposits of peat are compressed under sediments what is formed
coal
|
What does biomass mean
The total mass of a group of organisms
|
Terrestrial Autotrophs, which are land plants, convert inorganic carbon dioxide into organic compounds via
photosynthesis
|
true or false Methanogenesis yields the least amount of energy and takes place in the most extreme aerobic conditions.
false
|
What is peat
Peat is the surface organic layer of a soil that consists of partially decomposed organic matter, derived mostly from plant material, which has accumulated under conditions of waterlogging, oxygen deficiency, high acidity and nutrient deficiency.
|
When does combustion occur
It occurs when a substance/ substances burns,
|
what does the biosphere on the carbon cycle represent
living things
|
In aquatic ecosystems, carbon is present as dissolved carbon dioxide and
hydrogen carbonate
|
Anaerobic conditions refer to an environment or a situation where there is an
absence or limited availability of oxygen (O2)
|
What is one of the most common constituents of peat?
peat moss
|
What do petrol, natural gas, wood and coal have in common?
They are all fuels, which means that they can be burned to release energy
|
What is the lithosphere
the ground essentially
|
Carbon dioxide dissolves in water and combines with water to form?
carbonic acid
|
in autotrophs, the production of CO2 through respiration may occasionally balance the intake of CO2 via photosynthesis. this is known as?
the compensation point
|
Where does peat formation begin
in waterlogged environments
|
through oil and gas formation Anaerobic conditions are created by this burial, which also generates
heat
|
what are the products of incomplete combustion
carbon monoxide, carbon and water (soot)
|
