There would be significantly more CO2 in the atmosphere because plants take in CO2 during photosynthesis and fix the carbon into glucose.
The present levels of carbon dioxide dioxide in the atmosphere are causing global warming and climate change.
The Earth's oceans contain a huge amount of carbon dioxide in the form of bicarbonate and carbonate ions - much more than the amount in the atmosphere.
This means an increase in the amount of carbon dioxide (CO2) in the atmosphere. There is a normal balance of carbon dioxide in the atmosphere. Trees and green plants soak it up, and then when the trees rot or are burnt the carbon dioxide goes back into the atmosphere. However, more than 200 years ago we began seriously burning coal and oil. This released carbon dioxide that had been trapped millions of years ago. So over the years the amount of this gas in the atmosphere has been increasing. Most climate scientists agree that this increase in carbon dioxide is contributing to climate change and global warming.
False. Cyanobacteria changed earth's atmosphere by removing carbon dioxide and releasing oxygen.
If there were no plants it is unlikely that there would be any atmosphere at all. Plants remove carbon dioxide (CO2) from the atmosphere and are a vital part of the carbon cycle. No plants would mean huge increases of greenhouse gases in the air and a runaway greenhouse effect. Animals on the other hand would make little or no difference to the levels of carbon in the atmosphere.

The Fourth Report of the IPCC (The United Nations' Intergovernmental Panel on Climate Change), Climate Change 2007, said:The amount of carbon dioxide in the atmosphere in 2005 (379 ppm) exceeds by far the natural range of the last 650,000 years (180 to 300 ppm).
They added carbon dioxide to the atmosphere.
It is generally accepted that the increasing amount of carbon dioxide in the Earth's atmosphere is the cause of climate change. Many different factors affect the carbon dioxide level, but the burning of fossil fuel (coal, oil, natural gas) seems to be the most important factor.
Global warming means there is extra carbon dioxide into the atmosphere. This is putting an extra strain on the carbon cycle, which is unable to remove all the extra carbon dioxide.
Carbon dioxide is a naturally occurring greenhouse gas. At present concentrations, it helps maintain global temperatures at a level that is comfortable for humans and other animals that have adapted to the present climate. Increasing the amount of carbon dioxide in the atmosphere can result in global warming, by trapping more heat. This occurs when humans burn fossil fuels, manufacture cement of destroy forests.
