Never, CO2 is not harmful or poisonous in the atmosphere.
It IS poisonous in large concentrations in the oceans, as is produces carbolic acid which is not quickly removed by plankton. Algae blooms as a result of this and fertilizer runoffs produces dead zones at the mouths of rivers.
CO2 in the atmosphere is the second most prevalent greenhouse gas at about 400 parts per million (0.0004%) presently, behind water vapor, typically between 3 and 10%, dependent upon relative humidity.
Plants convert CO2 to oxygen and sugars by photosynthesis, there is not enough plant life to convert all the CO2 in the atmosphere. Plankton ( primarily, green algae and cyanobacteria) in marine environments provide about 70% of the free oxygen produced on Earth and damaging marine environments can destroy these.
**the term plankton also comprise micro-cellular animals (diatoms), it is a food source for many marine animals including baleen whale species. (humpbacks, right whales, blue whales, fin whales, minke whales and others)
Carbon dioxide (CO2) is the molecule that carries most of the carbon in the atmosphere.
Plants and trees absorb carbon dioxide during the process of photosynthesis. Additionally, oceans act as carbon sinks by absorbing and storing carbon dioxide from the atmosphere. Human activities such as afforestation, reforestation, and carbon capture and storage technologies also help in removing carbon dioxide from the atmosphere.
Carbon dioxide (CO2) is the molecule in which carbon is found in the Earth's atmosphere.
Carbon dioxide is released into the atmosphere when wood or coal is burned.
Carbon dioxide (CO2) is the gas that makes up 0.036 percent of Earth's atmosphere.
Carbon dioxide rises in the atmosphere.
Carbon dioxide is a waste product breathed out by living animals. Excessive intake of carbon dioxide can lead to carbon dioxide poisoning.
Carbon dioxide (CO2) is the molecule that carries most of the carbon in the atmosphere.
Yes, I think soil can emit carbon dioxide into the atmosphere.
The process of decay releases carbon dioxide into the atmosphere
Carbon Dioxide is toxic in large concentrations. Mild symptoms include nausea and muscle cramp, but carbon dioxide poisoning can be fatal in extreme cases.Not to be confused with carbon monoxide poisoning, which is harder to detect and a lot more dangerous.
Trees absorb carbon dioxide from the atmosphere during photosynthesis. When trees are cut down and not replaced, this carbon dioxide is no longer absorbed, leading to an increase in its levels in the atmosphere. Additionally, when trees are burnt or decompose, the stored carbon is released back into the atmosphere as carbon dioxide.
Carbon is stored in the atmosphere primarily as carbon dioxide (CO2) molecule.
Most of the carbon in the atmosphere is in the form of carbon dioxide, (CO2) gas.
About 95.3% of Mars' atmosphere is composed of carbon dioxide.
Well I know that the atmosphere has carbon dioxide in it, and when we breath out we release carbon dioxide that could be then added to the atmosphere.
