All plants need carbon dioxide to complete photosynthesis. Mammals take in oxygen and breath out CO2. It is the exact opposite for plants. The stomata on the plants act as lungs for the CO2 to enter the plant. The plant then puts out oxygen into the air. Since plants need CO2 and they are putting out oxygen, extra CO2 in the air will hope the plant grow.

The greenhouse effect keeps the earth warm by preventing all the sun's heat escaping back out into space. Carbon dioxide is one of several "greenhouse gases" that help in this…. Carbon dioxide captures some of this radiated heat and keeps it in the atmosphere. Some other greenhouse gases are water vapor, methane, nitrous oxide, and CFCs. In fact, any gas with three or more atoms acts as a greenhouse gas. Other greenhouse gases: Shortwave energy (that emitted by the sun) passes through the atmosphere pretty much unimpeded, ultimately to be intercepted by the ground. The warm ground emits longwave radiation in proportion to the fourth power of its temperature. In a completely dry, CO2-less and ozone-less atmosphere, this upwelling longwave radiation would all be lost to space. Carbon dioxide absorbs upwelling long wave radiation and re-emits it back to the ground, thereby reducing the amount of heat that escapes to space, warming the planet. The warmer planet evaporates more water, and the water vapor absorbs even more longwave radiation than the carbon dioxide, warming the planet even more. Incoming solar radiation is widely distributed across the electromagnetic spectrum. Some wavelengths (mostly visible light) get through the atmosphere to the surface, some don't. Of the radiation that gets through, some is reflected and some is absorbed by the surface of the earth. The reflected radiation is not an issue, because it goes right back into space at the same wavelengths that it came in at, unimpeded, just like on the way in. It is only the absorbed radiation that is a problem. This radiation is later re-emitted, but in the form of Infrared Radiation (IR). Certain atmospheric gases, known as "greenhouse gases", including carbon dioxide, absorb IR, then re-emit it back into the atmosphere. Some percentage of this re-emitted IR (after a long sequence of re-absorptions and re-emissions by other greenhouse gas molecules) eventually works its way back down to the lower atmosphere and is said to "warm" the surface. This is the "greenhouse effect". The "greenhouse effect", in and of itself, is a completely natural thing, and also a very good thing. Without it, the surface would be far too cold for life as we know it to exist. Greenhouse gases absorb, then re-emit the IR, in a completely random direction. It could go up, down, sideways, or any direction in between. Re-absorption by other greenhouse gas molecules complicates the path and destination of an individual unit of IR, but what it all boils down to is that something less than half of the IR absorbed by greenhouse gases eventually finds its way back to the surface, with the remainder escaping into space.
Yes - It's a greenhouse gas and the second most abundant making up 0.038% of our atmosphere. It is the most important man-made greenhouse gas (we produce it by burning fossi…l fuels like coal, oil and natural gas) and is responsible for global warming leading to climate change. However, all living organisms on Earth produce carbon dioxide through respiration, which is part of the carbon cycle. Without carbon dioxide in the air, plants could not perform photosynthesis. So it is not exclusively manmade.
It is needed to allow plants to grow and survive, but it helps to produce the enhanced greenhouse effect which is causing global warming and driving climate change.
The CO2 that is emitted via Respiration and is not reabsorbed via Photosynthesis exits the Cell and the greenhouse and moves into the atmosphere.
Methane, which comes from the stomachs of cattle and sheep, from thawing tundra, from food rotting in landfill and from drilling for oil and mining, is a greenhouse gas that i…s much more dangerous than carbon dioxide. A: The most prevalent and common greenhouse gas is water vapor, which accounts for up to 75% of all greenhouse warming. Methane accounts for well under 1% of the overall effect.
No, carbon dioxide (CO2) is NOT an effect of the greenhouse effect. It is one of the causes. With other greenhouse gases it is responsible for the natural greenhouse effect, a…nd the extra levels of CO2 from burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, are causing the enhanced (or accelerated) greenhouse effect which is why global warming is happening.
If your question is why do they do this, then it is to increase the rate of photosynthesis. The advantage of doing this is that by increasing the carbon dioxide concentration,… you increase the rate of photosynthesis, thus increasing the quality of the plants and allowing the market gardeners to profit more upon the selling of these plants (this is an advantage for the gardeners as opposed to anyone else). Advantages for the buyers of said plant could be that the plants grown in these high carbon dioxide concentrated environments are somehow more healthy or have better effects on the human body upon consumption.
atmospheric carbon dioxide allow infrared (heat) waves from the sun to come down to earth and warm whatever they hit. The warm objects on earth release some different wavele…ngths which cannot escape from the atmosphere, but are trapped and reflected back to earth, keeping more heat in causing global warming. Much like the glass/plastic roof of a greenhouse lets in light and solar heat and keeps it in so the plants in the greenhouse will heat up and grow.
Yes, it is part of the carbon cycle, that moves through the atmosphere and the biosphere.
Carbon dioxide is the main greenhouse gas. It also causes global warming.
For millions of years carbon dioxide, from the earth's natural carbon cycle, has worked to produce the greenhouse effect in the earth's atmosphere. The greenhouse gases, like …carbon dioxide, trap enough heat from the sun and stop it escaping into space. This keeps the earth comfortably warm enough for life. So some carbon dioxide is essential and useful. The present global warming is happening because extra carbon dioxide is being released from burning fossil fuels. Deforestation also means that there are not enough trees around to absorb carbon dioxide and keep the carbon cycle evenly balanced.
The carbon and water cycles of the earth are responsible for the normal greenhouse effect which keeps the earth warm enough for life. The greenhouse gases, including carbon di…oxide, capture and hold some of the heat being radiated out to space. Carbon dioxide (from burning fossil fuels) as well as deforestation is largely responsible for the enhanced greenhouse effect that is causing Global Warming and leading to climate change.
In a greenhouse, the glass or plastic panels trap solar energy inside the building, preventing it from reflecting back into space. Other human-induced gasses, but primarily ca…rbon dioxide and methane, have the same effect on our Earth's atmosphere.
No, greenhouse gases warm the air near the earth's surface by trapping heat from the warm earth that would otherwise escape into space.
