Because sedimentary rocks are formed from tiny animals which have died and fallen to the sea bed millions of years ago. Due to more substances falling onto the sea bed above the animals, they are pressurized underground. Due to the heat of Earth's core, the animals are burnt under the ground, turning into fossil fuels.
These animals contain carbon dioxide, and reduce the levels from the atmosphere by dying and travelling underground. This is how sedimentary rocks are a reason for reduced levels of carbon dioxide in the modern atmosphere.
Other reasons are that the carbon dioxide dissolved into oceans which were formed millions of years ago. Also, the formation of plants reduced the carbon dioxide levels due to photosynthesis, as they intake it and do not replace it, as they produce oxygen and glucose as a result of photosynthesis.
The carbon Dioxide levels in the Earth's atmosphere are rising.
We breathe out carbon-dioxide because high levels of carbon-dioxide in the body can be toxic By Akhilesh Sharma
Smoking increases carbon monoxide levels in the blood as opposed to carbon dioxide. Carbon monoxide ties up hemoglobin so that smokers have lower blood oxygen levels. Chronic inflammation has been linked to the high levels of carbon dioxide that smokers breathe in as it is 200 times the atmospheric rate.
The level of carbon dioxide in the air.
if the oxygen levels are too low, your muscles won't get the oxygen they need from the blood cells. if the carbon dioxide levels are too high, well, carbon dioxide is a waste product, the same thing will happen. this is why when you hold your breathe you pass out. if the muscles don't get the oxygen they need they can't move.
Chemoreceptors detect the levels of carbon dioxide in the blood.

In the mid-1700s the levels of carbon dioxide in the atmosphere were about 280 ppm (parts per million).In 2004 the levels of carbon dioxide in the atmosphere were about 375 ppm.In 2012 the levels of carbon dioxide in the atmosphere were about 393 ppm.
The scientist learn about carbon levels that in the atomosphere about carbon dioxide.
blood carbon dioxide levels
An increase in the atmospheric levels of carbon dioxide is the biggest contributor to global warming.

well, you don't breath carbon dioxide, you breath oxygen
Carbon dioxide levels increas
Not burning carbon compounds.
