Carbon dioxide in the atmosphere traps heat. scientists are concerned that too much carbon dioxide is being released into the air by human activity. using your knowledge of the carbon cycle, where do you think this carbon dioxide is coming from? list at least three possible sources of human-related carbon dioxide production. carbon dioxide is produced by the burning of fossil fuels.

Carbon dioxide is produced by the burning of fossil fuels. Carbon dioxide is produced by man-made machines. Carbon dioxide is produced by animal agriculture. Hope this helped or helped you get the right idea :p

Possible sources of human-related carbon dioxide production are:

Respiration: Humans and other living organisms produce carbon dioxide as a result of cellular respiration. This carbon dioxide is released into the atmosphere.

Burning of fossil fuels: Burning of fossil fuels such as petrol, coal, and natural gases produce a large amount of carbon dioxide in the atmosphere. These fossil fuels are used in almost all processes such as cooking, automobiles et cetera.

Industrial production of carbon dioxide: Industries or factories also burn a huge amount of fossil fuels which also release carbon dioxide in the atmosphere. In addition, different chemicals are used in factories, reactions of which also release carbon dioxide in the atmosphere.

idk and i also need to know where are those bio brainy acts lol
