Where do plants get carbon dioxide?
plase answer today
Why should the amount of carbon in the atmosphere today be reduced?
The present levels of carbon dioxide dioxide in the atmosphere are causing global warming and climate change.
What is the use of carbon dioxide in the sea?
Any use; body of waters absorb carbon dioxide. Today the absorbed carbon dioxide exeeded the normal limits and the pH of seas/oceans become more and more acidic.
What gases exist today but were absent from early earth's atmosphere?
is it carbon dioxide
What are high and low carbon dioxide levels?
Today the average concentration of carbon dioxide in the atmosphere is approx. 4oo vpm; some scientists consider that values over 300 ppm are high.
Where does the plant get carbon dioxide from?
It's in the air and we exhale carbon dioxide.A small percentage of the atmosphere is carbon dioxide. Carbon dioxide is released by the metabolic processes of organisms, and by our burning of fuels. In recent decades, the amount of carbon dioxide has increased so much, some scientists believe maintaining the current amount of carbon dioxide will devastate Earth's climate. Actually, today there were festivals held all over the world to make people aware of this issue. See http://www.350.org/

By our burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, which releases carbon dioxide.
How has the carbon dioxide in Our Atmosphere changed since 1750?
Levels of carbon dioxide in 1750 were approximately 275 parts per million. Today (2011) concentrations are approximately 392 ppm, an increase of more than 40 percent.
