How would the amount of carbon dioxide in the air change if earth had plants but no animals or people?
Without humans or animals, very little Co2 would be produced. Most of the worlds Co2 is from burning oil, gas, coal etc. Plants absorb it so the planet would be very healthy and in much cleaner than the way the world is today.
If plants don't have carbon dioxide to produce food, the cells of plants and animals break down food to produce energy, they give off carbon dioxide as a waste product.
How would the amount of carbon dioxide and oxygen in the atmosphere change if there were no animals?
If there were no animals on this planet that would cause a decrease in the levels of carbon-dioxide with a simultaneous increase in the levels of oxygen due to the photosynthesis.That would slowly cause a shortage of carbon dioxide leading to the extinction of plant kingdom finally leaving the atmosphere devoid of co2
The earth's atmosphere contains a small amount of carbon dioxide because of the amount of plants and bacteria which photosynthesise. The atmosphere used to be mainly carbon dioxiide until bacteria first evolved. When the bacteria evolved it photosynthesised, producing oxygen and taking in carbon dioxide, make the composition of the atmosphere change. Furthermore, the carbon dioxide dissolves in oceans, is used to form sedimentary rocks and animals and shells are carbon based. Fossil fuels are… Read More
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.
The present levels of carbon dioxide dioxide in the atmosphere are causing global warming and climate change.
When Carbon or any other organic compound udergoes combustion, carbon dioxide is produced alongwith a release of large amount of energy as heat. C + O2 = CO2
Plants and all kinds of vegetation, including grass, trees and rain forests absorb carbon dioxide and store it. About half the weight of a tree is carbon. Trees can store carbon for hundreds of years. Animals, including man, breathe out carbon dioxide into the atmosphere. Carbon is also released from soil, oceans and from rotting vegetation. This is all part of the natural carbon cycle. One animal, man, adds a lot of extra carbon dioxide… Read More
Plants do not change the Earth's atmosphere. Plants maintain the stable amount of oxygen and carbon dioxide in the atmosphere. Since humans breathe in oxygen and give out carbon dioxide, plants do the opposite during photosynthesis in the day, so as to reduce carbon dioxide in the environment. This is part of the natural carbon cycle. However, other industrial activities have been burning fossil fuels, giving out way too much carbon dioxide, and together with… Read More
The carbon cycle is the cycle in which carbon moves around...well, here's a "simple" description: Humans take in oxygen and change it to carbon dioxide. Burning things and the fire itself, also releases carbon dioxide. It's not just humans; it's also animals like dogs and cats that take in oxygen and give off carbon dioxide. We do it with every breath. So, how come we don't run out of oxygen and have carbon dioxide in… Read More
A balanced carbon cycle would be a situation in which the amount of carbon or carbon containing compounds that is consumed, is equal to the amount produced, so there is no change in the level of carbon available. An example would be an ecology in which the amount of carbon dioxide consumed by photosynthesis is equal to the amount of carbon dioxide released by animal metabolism and breathed out into the atmosphere - as long… Read More
Respiration (breathing) changes the amount of oxygen and carbon dioxide in the lungs
Frozen carbon dioxide is still carbon dioxide, so it is a physical change.
In my own opinion and un-tested hypothesis.... that carbon oxygen cycle start to change when there is no more plants to give oxygen and get carbon dioxide and there is no animals and humans that inhale oxygen and give off or exhale carbon dioxide.
plants do not change carbon monoxide into carbon dioxide. they, on the other hand, convert carbon dioxide in to oxygen.
Animals, including man, add carbon dioxide to the atmosphere by breathing it out, and by decomposing, when dead. Man also adds CO2 to the atmosphere by burning fossil fuels (coal, oil and natural gas), and by destroying forests. If there were no animals, including man, then the trees and other vegetation would grow again, with little to destroy them. Trees would absorb and store carbon, and the levels of carbon dioxide in the atmosphere would… Read More
That is true. Carbon dioxide (CO2), specifically the CO2 released by burning fossil fuels, and methane from ruminant animals and melting tundra are contributing to climate change.
How would the amount of the carbon dioxide in the atmosphere change if there were no plants and animal?
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.
If there were no plants, there would be no oxygen in the atmosphere and carbon dioxide would probably be the primary gas in the atmosphere. Plants absorb carbon dioxide and store it and release oxygen. About half the weight of a tree is carbon. Trees can store carbon for hundreds of years. This is all part of the natural carbon cycle.
Carbon Dioxide is a part of the cycle of plant and animal life. Carbon Dioxide is used by plants to manufacture sugars and the plants then give off oxygen as a byproduct. Animals such as people can breathe that oxygen in the air and change it back to carbon dioxide while metabolizing food. Other processes such as fire and rot also can produce carbon dioxide using the oxygen in the air. Burning of fossil fuels… Read More
No, it is not a change at all. Did you mean "a balloon filled with Carbon dioxide"
Yes and no. Bubbles of carbon dioxide effervescing from a soft drink is a physical change. Bubbles of carbon dioxide produced as vinegar reacts with baking soda is a chemical change.
Volcanoes release two gasses that can affect climate: carbon dioxide, and sulfur dioxide. Carbon dioxide is a greenhouse gas that traps heat in the lower atmosphere. Increasing the amount of carbon dioxide in the world can raise global temperatures. Sulfur dioxide will form tiny droplets in the upper atmosphere, reflecting sunlight and causing cooling.
When animals exhale, they release a gas called Carbon Dioxide (CO2) which can be lethal to animals if the gas is present in large quantities. Through the process of photosynthesis plants absorb carbon dioxide from the atmosphere and release oxygen as a byproduct. This helps animals because they need oxygen in order to breathe.
the cold air can change the carbon dioxide gas to a solid
Oxygen and carbon dioxide change in the lungs.
No. The formation of carbon dioxide is a change in physical state from the gas phase to the solid phase, which is a physical change.
Although the molecule is broken up it does not change the fact that it is carbon dioxide. Therefore you still have carbon dioxide.
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… Read More
Why are many governments trying to reduce the amount of carbon dioxide produced by burning fossil fuels?
Many governments, particularly in the European Union, are trying to reduce the amount of carbon dioxide produced by burning fossil fuels in order to slow global warming and cliimate change. Carbon dioxide is a greenhouse gas, and increases in atmospheric greenhouse gases contribute to rapid increases in average global temperatures.
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.
There would be significantly more CO2 in the atmosphere because plants take in CO2 during photosynthesis and fix the carbon into glucose.
Combining carbon dioxide and water is a chemical change, not a physical change, but it doesn't make sugar. Carbon dioxide and water makes carbonic acid. CO2 + H2O <--> H2CO3-->H+ + HCO3-
We breathe out carbon dioxide into the air, and trees take the carbon dioxide and change in into our oxygen. That is why trees are so important to us.
Yes, but at night. It make oxygen more than it does carbon dioxide though. ---- Plants, like animals, do have metabolisms by which energy is generated through the oxidation of sugar, which produces carbon dioxide. However, green plants consume much more carbon dioxide, in the process of photosynthesis, than they produce by means of their metabolism, and they produce much more oxygen than they consume.
It is the place in the body where carbon dioxide and oxygen change places in the lungs. It is the place in the body where carbon dioxide and oxygen change places in the lungs.
chemical and physical because some carbon dioxide is already in the air
Any increase in atmospheric carbon dioxide contributes to global climate change.
If carbon dioxide is leaving as a result of combustion of some organic material, then it is of course a chemical change.
Carbon dioxide is important in the atmosphere as it is one of the greenhouse gases that has been helping to keep the earth warm for millions of years. Not too much, not too little, but just the right amount. Unfortunately we are now adding too much carbon dioxide to the atmosphere, causing global warming and climate change.
Carbon dioxide is one of the greenhouse gases. By burning fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity (which releases carbon dioxide) man is causing global warming and climate change. This may not damage the earth, but it will certainly harm the people, birds and animals that live here.
i don't completely under stand your question, but if you're asking why the amount of it in the air doesn't change, the answer is simple. we breathe in oxygen and let out carbon dioxide. while plants "breathe in" carbon dioxide and let out oxygen. oxygen is also made from chemical reactions from the ocean. but this is not enough to supply this much life with oxygen, and we still don't know where all the extra… Read More
the carbon dioxide formed into carbon sugar molecules compound then they begin to change back.
Solid carbon dioxide is transformed directly in a gas by sublimation.
carbon dioxide escapes from upon the opening soda can is it chemical or physical
because they need carbon dioxide for photosynthesis they are just like humans but they take in carbon dioxide and then change it to oxygen and release it in the air
Trees do the process of photosynthesis. This is when the trees absorb carbon dioxide, store the carbon and release oxygen for all the other organisms to breathe. At the moment we have a lot of carbon dioxide in the air which is contributing to the greenhouse effect, global warming and climate change. By planting more trees, and not cutting as many down we can help reduce the amount of carbon dioxide in the air. this… Read More
When coal is burnt the chemical change combines carbon from the coal with oxygen from the air to produce carbon dioxide.
Carbon dioxide is acidic in nature. With water, it partially forms carbonic acid.
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).
The sublimation of dry ice into gaseous carbon dioxide is a physical change. It does not undergo any chemical changes.
