Most biofuels are not carbon neutral because the process of producing them often involves emissions from land use change, agricultural practices, and the use of fertilizers and pesticides. Additionally, the energy required to cultivate, harvest, and process the crops for biofuel production can contribute to greenhouse gas emissions.
What else can I help you with?
What organisms in the ocean store the most carbon?
Phytoplankton and marine algae are the primary organisms in the ocean that store the most carbon through the process of photosynthesis. They absorb carbon dioxide from the atmosphere and convert it into organic carbon, which can be stored in their cells or sink to the ocean floor when they die.
Which human activity would have the most direct impact on the oxygen carbon dioxide cycle?
Burning fossil fuels releases carbon dioxide that has been stored underground for 300 million years. This extra load is disrupting the carbon cycle, which is unable to move all the extra carbon dioxide out of the greenhouse gases in the atmosphere.
What is the most abundant atom in a lipid?
The most abundant atom in a lipid is carbon. Lipids consist mainly of carbon, hydrogen, and oxygen atoms, with carbon being the most prevalent due to its ability to form long hydrocarbon chains in lipid molecules.
What is the most common element of human body?
By molar amount, hydrogen and oxygen are the most common elements; carbon is the third. By mass, oxygen is the most common, and carbon is the second (with hydrogen being third by mass). By mass, oxygen is the most abundant, and phosphorus is the least, carbon the 2nd, hydrogen, 3rd. By atoms, hydrogen is most abundant, and phosphorus the least, oxygen 2nd, carbon 3rd.
At what pH level does catalase work most effectively?
Catalase works most effectively at a pH level of around 7, which is considered neutral.
What produces the most carbon monoxide?
The burning of fossil fuels, such as gasoline and coal, produces the most carbon monoxide.
How burning of wood and other fuels is most closely related to the cycling of which material?
The burning of wood and other fuels is most closely related to the cycling of carbon. When wood and fuels are burned, carbon is released into the atmosphere as carbon dioxide (CO2), contributing to the carbon cycle by transferring carbon between the atmosphere, plants, and other parts of the ecosystem.
What chemicals are inside fuels?
Most fuels consist of various combinations of the elements carbon, hydrogen, and oxygen.
What cycle is most affected when burning of fossil fuels by cars and factories?
The carbon cycle is most affected by the burning of fossil fuels. When fossil fuels are burnt, carbon dioxide is released into the atmosphere, contributing to the greenhouse effect and global warming. This disrupts the natural balance of the carbon cycle, leading to various environmental impacts.
When human burn fossil fuels most of the carbon quickly enters the blank as carbon dioxide?
atmosphere
What do all fuels have in common?
The most common element in all combustible fuels is Hydrogen, this is closely followed by the presence of Carbon.
What is the gas released by most fuels after combustion?
Carbon dioxide (CO2) is the gas released by most fuels after combustion. It is a greenhouse gas that contributes to climate change.
What is the source of the most of the carbon?
The most important source of carbon entering atmosphere is industries. Living things, burning fossil fuels and automobiles are other sources of carbon dioxide.
What is the common atom in fossil fuel?
Carbon Most common in all fossil fuels is carbon. In natural gas, both hydrogen and carbon are common.
What does most of the carbon in fossil fuels exist of?
carbon is an element, so "carbon" can't exist of anything. But the carbon found in fossil fuels are mostly from shells and dead animals or plants, after being exposed to imense heat and presure by stacking layers of sediment, plants and shells
Most fuels are hydrocarbons. what does this mean?
It means that fuels are composed of molecules containing only hydrogen and carbon atoms. These hydrocarbon molecules release energy when burned, making them suitable for use as fuels in engines and heaters. Examples of hydrocarbons include gasoline, diesel, and natural gas.
Where does most of the Carbon produced from burning fossil fuels end up?
It goes into the atmosphere as carbon dioxide. The heat produced by burning fuel comes from forming the carbon-oxygen chemical bonds that creates CO2.
