Sentences with phrase «carbon dioxide increase photosynthesis»

Not exact matches

Taken together, the research data provides a picture, from the leaf scale to the global scale, suggesting that droughts in the Amazon basin are affecting levels of carbon dioxide in the atmosphere globally, both on a short - term basis though decreasing photosynthesis and on a longer term basis, by increasing tree mortality.

The simulations suggested that the indirect effects of increased CO2 on net primary productivity (how much carbon dioxide vegetation takes in during photosynthesis minus how much carbon dioxide the plants release during respiration) are large and variable, ranging from less than 10 per cent to more than 100 per cent of the size of direct effects.

«A higher concentration of carbon dioxide in our atmosphere would aid photosynthesis, which in turn contributes to increased plant growth,» Rep. Lamar Smith (R — Texas) wrote in an op - ed last year.

Although natural photosynthesis plays a vital role in absorbing and «fixing» carbon dioxide emitted from fossil fuel use, it has not prevented the net increase of this gas in the atmosphere since the Industrial Revolution.

For many crops more carbon dioxide means a rise in the rate of photosynthesis and, therefore, in growth; and with increased carbon dioxide some plants» use of water is more efficient, according to studies done in conventional glass greenhouses.

Doubling of the carbon dioxide concentration will cause global plant photosynthesis to increase by about one third, according to a paper published in the journal Nature.

It is widely accepted that plant photosynthesis will increase with carbon dioxide, so long as nutrients, such as nitrogen and phosphorus, are not limiting.

Global Earth System Models (ESMs) all predict that global photosynthesis will increase with carbon dioxide, but they differ by a factor of three in the size of this «CO2 fertilization».

Reduced nitrogen content in atmospheres with raised carbon dioxide has previously been attributed to a kind of dilutive effect, in which nitrogen absorption fails to keep pace with the increase in plants» photosynthesis and growth.

Initially, an increase in carbon dioxide in the atmosphere — a key ingredient for photosynthesis — led to a growth spurt for the Amazon's trees, the researchers say.

For example, he said, most participants recognized that carbon dioxide increases global temperatures, yet mistakenly indicated that rising levels of atmospheric CO2 are expected to «reduce photosynthesis in plants.»

In addition to rising temperatures, the report discussed a variety of «other possible effects of an increase in atmospheric carbon dioxide», including melting of the Antarctic ice cap, rise of sea level, warming of sea water, increased acidity of fresh waters (which also applies to the danger of ocean acidification, global warming's evil twin), and an increase in plant photosynthesis.

So, consistent with previous research, the study finds that trees can use water more efficiently when there's more carbon dioxide in the air, which makes their rate of photosynthesis increase.

The research also counters the optimistic projections of some climate change sceptics, who argue that more carbon dioxide in the atmosphere will increase plant growth, as they take up carbon from the air for photosynthesis.

The carbon dioxide rich exhaust is then purified and fed into the atmosphere of the skyfarm to increase food production and convert it back to oxygen through photosynthesis.

As more carbon dioxide dissolves into the water column, phytoplankton are able to increase their rate of photosynthesis, resulting in the production of more dissolved organic matter and the release of various nutrients.
