Sentences with phrase «atmosphere by photosynthesis»

If ozone is contained in the atmospheres of an extrasolar planet, it is assumed that the planet has some living organisms that generate oxygen by photosynthesis because ozone is made up of oxygen.

For example, carbon dioxide, the dominant form of carbon in the atmosphere and associated with climate change, is used by plants to generate energy via photosynthesis.

This creation of oxygen by photosynthesis changed our planet's atmosphere and made our lives possible.

Not so much by direct photolysis of water vapor (not generally a lot of that in the stratosphere), but from CH4, which could build up in a nearly oxygen - free atmosphere, and being largerly of biotic origin, with the H coming from photosynthesis (releasing O); O2 buildup itself was delayed because of geologic O2 sinks (in particular, the conversion of ferrous Fe (naturally present in the crust and mantle and which can dissolve in the oceans) to ferric Fe (precipitates out of the water, the source of banded - iron formations, which humans have used to get Fe).

But also, it absorbs CO2 from the atmosphere, via its leaves, and by the process of photosynthesis converts that to organic (carbon based) compounds.

However, the carbon you exhale into the atmosphere was recently removed from the atmosphere by plants during photosynthesis, yielding a net change of zero.

Looking at the carbon fixation - organic material decomposition as a linked process, one sees that some of the carbon fixed by photosynthesis and incorporated into plant tissue is perhaps delayed from returning to the atmosphere until it is oxidised by decomposition or fire.

Radiocarbon is sequestered by trees via photosynthesis, moved to the ground, and finally released again into the atmosphere.

Since decreased plant and soil respiration could not explain the drop in carbon dioxide entering the atmosphere in 1992 and 1993, Gu and his colleagues deduced that enhanced photosynthesis by plants must be involved.

Carbon dioxide has constantly been removed from the atmosphere by precipitation and photosynthesis.

When photosynthesis intensifies, plants remove more carbon dioxide produced by fossil fuels from the atmosphere.

But Anesio's team has also found that organisms in these holes can have a cooling effect on the planet by actively sucking carbon dioxide out of the atmosphere through photosynthesis.

But of course, when it's pointed out that not all absorption of electromagnetic radiation creates heat, for example in photosynthesis when it converts to chemical energy and not heat energy and in the atmosphere where absorption of visible light by the electrons of the molecules of nitrogen and oxygen which spit out the same non-thermal energy that went in, this is ignored.

The climate catastrophists attempt to create fear by mentioning the carbon cycle but just happen to omit that significant oxygenation of the atmosphere took place when the planet was in middle age and this process of photosynthesis resulted the recycling and sequestration of carbon.

In the short - term cycle, carbon in the atmosphere is turned into plant material by photosynthesis, then returned to the atmosphere by processes like animal digestion.

This indicates that replacing missing iron back into the ocean could stimulate phytoplankton based photosynthesis and generate improvements to the ocean ecosystem, while removing carbon dioxide from the atmosphere as it is consumed by photosynthesis.

A potentially game - changing breakthrough in artificial photosynthesis has been achieved with the development of a system that can capture carbon dioxide emissions before they are vented into the atmosphere and then, powered by solar energy, convert that carbon dioxide into valuable chemical products, including biodegradable plastics, pharmaceutical drugs and even liquid fuels.

CO2 is removed from the atmosphere by plant photosynthesis (123 ± 8 PgC / year).

«Two processes remove CO2 from the atmosphere: photosynthesis by land plants and marine organisms, and dissolution in the oceans.»

@Jimbo — If you really want to put it in perspective, until about 2 to 1-1/2 billion years ago, before photosynthesis by blue - green algae converted almost all of it to oxygen, the Earth's primordial atmosphere was about 20 percent CO2, about the same percentage as oxygen is today, and the Earth certainly didn't burn up them even with 500 times as much CO2 in the air as there is today.

The Carbon Cycle Photosynthesis takes CO 2 out of the atmosphere Cell Respiration by all organisms puts CO 2 into the atmosphere Transfer.

Breathing or wood burning doesn't add extra CO2 to the atmosphere, because what we breath or use as firewood was removed as CO2 from the atmosphere months to years before by photosynthesis... In contrast, fossil fuels were removed from the atmosphere many millions of years ago and now it is one - way addition...

The cost for carbon sequestration with wood burial is low because CO2 is removed from the atmosphere by the natural process of photosynthesis at little cost.

These parameters regulate processes such as plant carbon uptake by photosynthesis and how precipitation is separated into evapotranspiration to the atmosphere and river runoff.

In contrast, fossil fuels come from ancient photosynthesis, thus the carbon released by burning had been stored for ages and thus represents a net addition into the atmosphere.

The circulation of CO2 in and out of the atmosphere is due mainly to the photosynthesis which takes CO2 molecules out from the atmosphere and the returning of these molecules to the atmosphere by means of combustion and moldering.

This happens because biofuels — fuels derived from recent photosynthesis — are basically carbon neutral because all carbon released by burning has recently been taken from the atmosphere.

The main natural sinks are the oceans and plants and other organisms that use photosynthesis to remove carbon from the atmosphere by incorporating it into biomass.

The biggest flows out of the atmosphere are photosynthesis on land and CO2 uptake by cold ocean water.

Because the source of carbon is plant matter (foods and other farm crops), the net flux of carbon to the atmosphere from these sources is assumed to balance the carbon being sequestered annually by photosynthesis.

The land - based carbon cycle works as plants take CO2 out of the atmosphere and convert it to organic material by photosynthesis.

Simply speaking, volcanoes helped form the atmosphere while living organisms have helped shape the atmosphere to their liking in two ways: firstly by warming the planet to a liveable temperature by producing methane and carbon dioxide during the process of decay of dead matter, and secondly by creating oxygen through the process of photosynthesis by our green friends in the plant kingdom.
