Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas. Each year, five and a half billion tons of carbon is released by burning fossil fuels.
Q. What is one reason that the carbon cycle important?
The carbon cycle is important in ecosystems because it moves carbon, a life-sustaining element, from the atmosphere and oceans into organisms and back again to the atmosphere and oceans.

Q. How does the carbon cycle affect the atmosphere?
The carbon cycle plays a key role in regulating Earth’s global temperature and climate by controlling the amount of carbon dioxide in the atmosphere. The greenhouse effect itself is a naturally occurring phenomenon that makes Earth warm enough for life to exist.
Q. What three ways does carbon get put back into the atmosphere?
Respiration, excretion, and decomposition release the carbon back into the atmosphere or soil, continuing the cycle.
Q. What causes CO2 to decrease in the atmosphere?
Formation of sedimentary rocks. Carbon dioxide is a very soluble gas. As the oceans formed, carbon dioxide dissolved to form soluble carbonate compounds so its amount in the atmosphere decreased.
Q. What happens if carbon dioxide levels are too low on earth?
Decreased Temperatures Because carbon dioxide traps heat in the atmosphere, a lessening of atmospheric carbon dioxide concentrations would mean that more heat could escape into space. This would result in a net decrease in the Earth’s average temperature, assuming other factors remain the same.
Q. What if there was less carbon?
The Short Answer: Carbon is in carbon dioxide, which is a greenhouse gas that works to trap heat close to Earth. It helps Earth hold the energy it receives from the Sun so it doesn’t all escape back into space. If it weren’t for carbon dioxide, Earth’s ocean would be frozen solid.
Q. What happens when CO2 decreases?
When carbon dioxide concentrations drop, Earth cools, some water vapor falls out of the atmosphere, and the greenhouse warming caused by water vapor drops.
Q. What is the highest level of CO2?
419 parts per million
Q. What is the current CO2 level for Earth?
409.8 parts per million
Q. What level of CO is acceptable?
A passive monitor is currently under development. No standards for CO have been agreed upon for indoor air. The U.S. National Ambient Air Quality Standards for outdoor air are 9 ppm (40,000 micrograms per meter cubed) for 8 hours, and 35 ppm for 1 hour.
