What gas is increased in the air you breath out?
Carbon dioxide.
What happens when concentration of carbon dioxide is increased?
When concentration of carbon dioxide increases, global warming increases. This causes ozone depletion.
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/
Why do environmentalists believe that carbon dioxide emissions have increased?
At this time we are seeing rapid industrialization in China and India; conservation measures in the western world have not come close to offsetting the increased emissions from developing economies. Carbon dioxide emissions have increased.
Where do the carbon atoms come from to produce the certain sugar for photosynthesis?
From the animals around it breathing oxygen and converting it to carbon dioxide.
Scientists who are concerned about increased carbon dioxide in the atmosphere believe global warming is caused by?
... the burning of fossil fuels, which is adding extra carbon dioxide to the greenhouse gases in the atmosphere.
How do scientists think that increased carbon dioxide levels contribute to global warming?
Carbon dioxide is a greenhouse gas. Greenhouse gases capture and retain the sun's heat. Increased carbon dioxide levels mean that more and more of this heat is retained. This is warming the earth and the atmosphere all round the world - global warming.
Why happens to rabbits when carbon dioxide is increased?
If you mean adding carbon dioxide to a rabbit's local environment, they would likely asphyxiate when the concentration of CO2 passed a certain level.
What greenhouse gas do scientists believe has increased due to pollution?
Carbon dioxide, from the burning of coal, oil and natural gas, the fossil fuels.
What organism are scientists using to eat carbon dioxide?
To reduce the amount of carbon dioxide in the atmosphere, scientists are planting more green plants e.g. forests. Green plants require carbon dioxide for photosynthesis.
What gas is increased in the air you breath out?
Carbon dioxide.
What happens to the blood concentration level of carbon dioxide following increased breathing?
With increased breathing, levels of carbon dioxide in the blood drop and levels of oxygen rise.
An increased rate of breathing as a result of an increased buildup of carbon dioxide in the bloodstream would be best described as an example of?
An increased rate of breathing as a result of an increased buildup of carbon dioxide in the bloodstream would be best described as an example of?
What has happened to global temperatures as atmospheric levels of carbon dioxide have increased?
They both have increased.
Where do scientists think extra carbon dioxide is coming from?
FACTORY
Humans have greatly increased the level of in the atmosphere?
carbon dioxide
Cyanobacteria increased the levels of carbon dioxide in the atmosphere.?
true
