Carbon dioxide is important because it is used in photosynthesis, a process that is necessary for the survival of life on Earth. Carbon dioxide is also a vital greenhouse gas that helps trap heat in the atmosphere, and it plays a key role in Earth's carbon cycle.

Carbon dioxide is a colorless, non-organic compound that is a gas at room temperature and comprises about 0.03 percent of Earth's atmosphere. It is produced when materials that contain carbon are combusted, and it is one of the most prevalent greenhouse gases that trap heat within the Earth's atmosp

Carbon dioxide is generated through the oxidation of carbon or carbon compounds, including combustion and cellular respiration. Carbon dioxide is also released into the atmosphere when water thaws, as well as during volcanic eruptions. While many fear its theorized effects on global temperatures, ca

Doctors test the levels of carbon dioxide in the blood by measuring the patient's blood bicarbonate levels, according to MedlinePlus. They draw blood from a vein on the inside of the elbow or the back of the hand. Doctors test the carbon dioxide levels in the serum, or the liquid part of blood.

The normal blood carbon dioxide levels is 23 to 29 milliequivalents per liter (mEq/L). The level of carbon dioxide in the liquid component of the blood is measured by a test called CO2 blood test. The mEq/L value represents 1,000th parts of a substance that is dissolved in 1 liter of plasma or solut

A high level of carbon dioxide in the blood may indicate conditions such as Cushing's syndrome or hyperaldosteronism, according to MedlinePlus. Those who have breathing disorders or who have been vomiting may also have high levels of carbon dioxide in the blood.

Test for carbon dioxide by burning a splint, using litmus or indicator papers or running the gas through lime water. Additionally, according to the National Institutes of Health, a blood test can be performed to determine the amount of carbon dioxide in a person's blood.

The kidneys and lungs filter carbon dioxide from the body, and high levels normally indicate certain medical conditions, none of which is treated with food, according to Healthline and WebMD. Often, high carbon dioxide levels, or acidosis, indicate a lung or metabolic health condition.

Plants use carbon dioxide to produce food. Through photosynthesis, they convert carbon dioxide and water into sugar. They derive energy from the sun to transform carbon dioxide into glucose and oxygen.

Plants get carbon dioxide from the air that surrounds them. The carbon dioxide from air naturally diffuses through extremely small pores in the leaves of plants.
