Some actions that release CO2:
Nature through the carbon cycle provides 97%.
Burning of fossil fuels (coal, oil and natural gas) releases extra carbon long-hidden underground.
Power plants generating electricity. Cars, trucks and planes burning petroleum products
Humans and animals produce it when they breathe out, oxygen goes in, carbon dioxide comes out.
Breathing: people, animals and plants (which respire carbon dioxide at night).
Opening a soft drink bottle, or beer - all the bubbles are carbon dioxide.
Chemical reactions, like bicarb soda and vinegar.
Yeast doing its thing, like making bread light and fluffy.
Drive a car, breath, practically anything that has an engine releases carbon dioxide when it is used.
Any burning (with oxygen) of carbon containing fuels: hydrocarbons, carbohydrates, alcohol, carbon black, natural gas, petrol etc. releases carbon dioxide (and mostly also dihydogen monoxide)
Carbon dioxide (CO2) is carried from cells by the blood and exchanged for oxygen in the lungs. The CO2 is then exhaled when we breathe out.
The organ in our body that gives out carbon dioxide is the lungs.
The lungs expel carbon dioxide.
The lungs
Carbon dioxide is not an air pollutant. However excessive carbon dioxide release into the atmosphere is a pollutant as it contributes to acid rain
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.
It means that there is more carbon dioxide (unbreathable air) gets in to are air
Yes, respiration does add carbon dioxide to the air
Fossil fuels are mainly made up from hydrogen and carbon atoms. When you burn them the oxygen in air chemically reacts with the hydrogen and carbon to produce carbon dioxide and water.

The blood carries the carbon dioxide from the body cells to the lungs so the lungs can release the carbon dioxide when you exhale
Humans do, and all animals! We breathe in O2 and breathe out CO2.
Blood containing carbon dioxide flows from veins throughout the body to the heart, and then the heart pumps it to the lungs. Small air sacs (alveoli) in the lungs remove the carbon dioxide from the blood and release it into the lungs where it is exhaled.
Yes, they breathe in air, which contains about 21% oxygen and release carbon dioxide.
carbon dioxide
As fossil fuels are made up of Carbon and Hydrogen. This burns in oxygen (in air) to form Carbon dioxide and Water, so the carbon dioxide is released into the air
There are a number of internal organs that help carbon dioxide to be released into the air. The two lungs are the major players with the heart and circulatory system helping.
we breathe in oxygen and we release carbon dioxide
