Biomass is vegetable matter, like unwanted parts of sugar cane (bagasse), as well as residue from tree felling and other things. When vegetation grows, it removes carbon dioxide (CO2) from the atmosphere. When the same material is burnt as biomass, that same CO2 is put back into the carbon cycle.
What else can I help you with?
Why doesn't burning biomass add extra carbon to the atmosphere?
Burning biomass doesn't add extra carbon to the atmosphere because the carbon released during combustion is part of the natural carbon cycle. Biomass, such as plants, absorbs carbon dioxide from the atmosphere during photosynthesis. When it is burned, the carbon is released back into the atmosphere, but this is a re-release of carbon that was previously absorbed, maintaining a balance as long as new plants continue to grow and sequester carbon. Thus, it is considered carbon-neutral over the short term, assuming sustainable management of biomass resources.
Which gas is added to the atmosphere in the process of combustion?
During the process of combustion, carbon dioxide (CO2) is the primary gas added to the atmosphere. This occurs when carbon-containing fuels, such as fossil fuels and biomass, are burned in the presence of oxygen, resulting in the release of energy and the formation of CO2 as a byproduct. Additionally, combustion can also produce other gases, such as water vapor (H2O) and various pollutants, depending on the fuel and combustion conditions.
How does carbon monoxide enter the atmosphere?
Carbon monoxide enters the atmosphere primarily through the incomplete combustion of fossil fuels and biomass. This can occur during the burning of wood, vehicle exhaust, industrial processes, and wildfires.
What 2 processes put carbon back into the atmosphere?
Two key processes that put carbon back into the atmosphere are respiration and combustion. During respiration, living organisms, including animals and plants, break down glucose for energy, releasing carbon dioxide as a byproduct. Combustion occurs when organic materials, such as fossil fuels or biomass, are burned, releasing stored carbon into the atmosphere as carbon dioxide.
Is Respiration is the only major process through which carbon moves from organic molecules back to the atmosphere?
No, respiration is not the only major process through which carbon moves from organic molecules back to the atmosphere. While respiration by organisms releases carbon dioxide as they break down organic matter for energy, other processes such as combustion (burning fossil fuels and biomass) and decomposition by microorganisms also contribute significantly to the release of carbon dioxide into the atmosphere. Additionally, processes like volcanic eruptions can release carbon stored in the Earth's crust.
How does carbon leave the biomass?
Carbon can leave the biomass through processes like respiration, decomposition, and combustion. During respiration, organisms release carbon dioxide back into the atmosphere. Decomposition of dead organic matter also releases carbon as it breaks down. Additionally, combustion of biomass or fossil fuels releases carbon dioxide into the atmosphere.
Why doesn't burning biomass add extra carbon to the atmosphere?
Burning biomass doesn't add extra carbon to the atmosphere because the carbon released during combustion is part of the natural carbon cycle. Biomass, such as plants, absorbs carbon dioxide from the atmosphere during photosynthesis.

Thus, it is considered carbon-neutral over the short term, assuming sustainable management of biomass resources.
What are three ways that carbon is returned to the atmosphere?
Carbon is returned to the atmosphere through several processes, including respiration, combustion, and decomposition. During respiration, living organisms release carbon dioxide as they break down glucose for energy. Combustion of fossil fuels and biomass also releases stored carbon into the atmosphere as CO2. Additionally, the decomposition of organic matter by microbes and other decomposers releases carbon back into the atmosphere.
What are ways of 3 carbon enters the atmosphere?
Three carbon enters the atmosphere primarily through processes such as respiration, combustion, and decomposition. During respiration, animals and plants release carbon dioxide (CO2) as they convert glucose into energy. Combustion of fossil fuels and biomass, such as wood and coal, also releases CO2 into the atmosphere. Additionally, decomposition of organic matter by microorganisms emits carbon dioxide as they break down dead plants and animals.
How does carbon monoxide enter the atmosphere?
Carbon monoxide enters the atmosphere primarily through the incomplete combustion of fossil fuels and biomass. This can occur during the burning of wood, vehicle exhaust, industrial processes, and wildfires.

How does carbon move from living things in the atmosphere?
Carbon moves from living things to the atmosphere through processes such as respiration, decomposition, and combustion. During respiration, organisms release carbon dioxide into the atmosphere. Decomposition of dead organisms also releases carbon dioxide. Combustion of fossil fuels by humans is another significant way carbon is released into the atmosphere.
What does carbon enters the atmosphere?
combustion
How does carbon leave the biosphere?
Carbon leaves the biosphere through processes such as respiration, decomposition, and combustion. When organisms respire, they release carbon dioxide back into the atmosphere. Decomposition of organic matter and combustion of fossil fuels also contribute to carbon leaving the biosphere and entering the atmosphere.
Is Respiration is the only major process through which carbon moves from organic molecules back to the atmosphere?
No, respiration is not the only major process through which carbon moves from organic molecules back to the atmosphere. While respiration by organisms releases carbon dioxide as they break down organic matter for energy, other processes such as combustion (burning fossil fuels and biomass) and decomposition by microorganisms also contribute significantly to the release of carbon dioxide into the atmosphere. Additionally, processes like volcanic eruptions can release carbon stored in the Earth's crust.
Why is biomass described as carbon neutral?
Biomass is considered carbon neutral because the carbon dioxide released during its combustion is equal to the amount of carbon dioxide that the biomass absorbed during its growth. This creates a balance in the carbon cycle, making biomass a renewable energy source with minimal impact on the environment.
