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.

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.
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.
Is Photosynthesis is the main process by which carbon dioxide moves from the atmosphere to biomass?
no
Why does the carbon dioxide released by burning biomass not result in global warming?
When biomass burns, it releases carbon dioxide that was previously stored in plants during photosynthesis. The carbon in the biomass is part of the natural carbon cycle, so burning it does not add new carbon to the atmosphere like burning fossil fuels. Additionally, as new biomass grows, it absorbs carbon dioxide through photosynthesis, creating a cycle that does not contribute to the accumulation of carbon dioxide in the atmosphere.
What is a gas released into the atmosphere by combustion called?
Carbon dioxide (CO2) is the gas released into the atmosphere by combustion of fossil fuels.
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.
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.
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.
How is energy released within biomass fuels?
Energy is released from biomass fuels through the process of combustion, where the fuel is burned in the presence of oxygen. During combustion, the carbon and hydrogen in the biomass react with oxygen to release heat energy in the form of heat and light. This energy can be harnessed to produce heat, electricity, or other forms of energy.
Is Photosynthesis is the main process by which carbon dioxide moves from the atmosphere to biomass?
no

Additionally, as new biomass grows, it absorbs carbon dioxide through photosynthesis, creating a cycle that does not contribute to the accumulation of carbon dioxide in the atmosphere.
What are 2 natural processes that release carbon into the atmosphere?
Respiration by living organisms, such as plants and animals, releases carbon dioxide into the atmosphere. Decomposition of organic matter by bacteria and fungi also releases carbon into the atmosphere.
What is a gas released into the atmosphere by combustion called?
Carbon dioxide (CO2) is the gas released into the atmosphere by combustion of fossil fuels.
Why is biomass a better alternative than coal?
The main advantage of biomass over coal is that it is "carbon neutral". This means that in order for the biomass to be created, it consumed carbon dioxide from the environment. Upon burning biomass, no additional carbon is added to our atmosphere. Coal, on the other hand, is taking carbon out of the earth and adding more to our atmosphere.
