This depends both upon their Size and what they use for their source of Energy.
In terms of total human output of CO2, we produce about 6% of the total annually produced CO2. The rest is a naturally occurring release. In terms of tonnes of CO2, the total is about 6 gigatonnes. The atmosphere holds about 720 billion tons of CO2.
About 7 billion tons of coal is presently mined each year. While some of this is used to make coke for steel blast furnaces, most of it ends up being burned in coal power plants. Coal is carbon twelve, but during oxidation it combines with diatomic oxygen (O16) to form CO2. In other words, one ton of coal releases over 2.8 tons of CO2.
World wide, nearly 20 billion tons of CO2 is emitted by coal fired power plants each year, at the present time. As China and other nations continue expanding coal production, this is expected to rise a little bit in the ensuing years.
This is almost an impossible number of accurately determine. The power consumed by the manufacture of food is the primary cause of CO2. The energy used by tractors to plant and harvest also contribute. As far as man's contributions to CO2 levels this is a non deal issue. Over half of man's CO2 production is from heating and cooling homes. A large portion of the remaining is from our transportation issues. This leaves only a very small portion of our output left to be blamed on other things.
Man produces about 6% of all CO2 and about 0.28% of all greenhouse gases.
When the steam boilers or blast furnaces, etc. are used, the fires may not be drawing enough oxygen resulting in incomplete combustion causing the emissions to contain carbon monoxide (CO) which is a poisonous gas. Complete combustion (sufficient oxygen) results in emissions containing carbon dioxide (CO2) which is not only safe to breathe but is imperative to sustain plant growth. Many factories monitor the flue gases in the exhaust to ensure enough oxygen (O2) is present for complete combustion but sometimes the air supply is not enough. It is the fires that cause the release of carbon dioxide which is contributing to global warming.
If you count coal fired power plants as factories, emissions are in the neighborhood of 15 to 20 billion tons per year.
Carbon dioxide is in the air we exhale. Cars and factories also release carbon dioxide which pollutes the air. It depends which ecosystem. It is primarily taken up by the ocean and terrestrial ecosystems. In the latter, this is primarily through photosynthesis.
trees suck in carbon dioxide to then release oxygen
Carbon dioxide is not an air pollutant. However excessive carbon dioxide release into the atmosphere is a pollutant as it contributes to acid rain
Some of the process that fix carbon dioxide are limewater + carbon dioxide equals calcium carbonate + water. Another is calcium carbonate + water + carbon dioxide = aqueous calcium bicarbonate. These equations work in reverse to release carbon dioxide.
It depends, but most is CO2(carbon dioxide) and CH4(methane) :)

Normally factories will be hit by CO2
Animals breathe in oxygen and release carbon dioxide. Plants absorb carbon dioxide and release oxygen.
Through Factories and power stations burning fossil fuels (coal etc.). You can see the carbon dioxide spewing from the chimneys of factories. also cars produce CO2 (carbon dioxide) through the burning of petrol and diesel.
Only factories that use and burn coal produce carbon dioxide into the atmosphere. Forest fires and humans produce the most carbon dioxide.
Cars and factories.
The burning of fossil fuels from factories and businesses release carbon-dioxide into the atmosphere, causing pollution and acid rain.
More living things such as humans are being brought into existence, breathing out more carbon dioxide. Factories, cars and planes also contribute to rising carbon dioxide and carbon monoxide in the atmosphere from the smoke they release. Plants such as trees are supposed to convert the carbon dioxide into oxygen, but we keep cutting them down. In short - because of the human race.
Plants release carbon dioxide during the night time
trees absorb carbon dioxide and release oxygen
All animals are effected. We all release carbon Dioxide as we exhale, and then the trees and plants surrounding absorb the Carbon Dioxide, and release oxygen.
