随着二氧化碳浓度的增加,植物的光合作用会在一定程度上加剧全球变暖,再结合第二段的“The CIS scientists unveiled new research that shows increased carbon dioxide levels cause plants to keep water that otherwise would have evaporated (蒸发)from their leaves, entered the atmosphere and helped cool the ...
根据划线句上一句Plants were expected to get larger with increased carbon dioxide in the atmosphere,可知,预计随着大气中二氧化碳的增加,植物会变大。而接下来的but说明的相反的结果可知句子 but changes in temperature, humidity(湿度)and nutrient availability seem to have trumped the benefits of increased ...
The chapter describes the processes affecting carbon isotope exchange between plants and the atmosphere. There is a significant difference between long-term isotope discrimination and short-term "on-line" measures of discrimination. The reasons for this remain to be determined, but fractionations post...
8."Plants were supposed to grow larger with increased carbon dioxide in the atmosphere,but changes in temperature,humidity and nutrient availability seem to have trumped the benefits of increased carbon dioxide,"said researchers from the National University of Singapore. ...
Carbon dioxide (CO 2 ) is considered a trace gas in the atmosphere because it is much less abundant than oxygen or nitrogen. However, this trace gas plays a vital role in sustaining life on Earth and in controlling the Earth's climate by trapping heat in the atmosphere. ...
"Plants were expected to get larger with increased carbon dioxide in the atmosphere, but changes in temperature, humidity, and nutrient availability seem to have trumped the benefits of increased carbon dioxide, " said researchers from the National University of Singapore. 45 percent of the species...

The chemical weathering of Ca-Mg silicate rocks is the principal process whereby CO2 is removed from the atmosphere on long or multimillion-year time scales. At present vascular land plants exert an important influence on weathering by recycling water and by bringing about the secretion of acids ...
aThus ,not only is more carbon dioxide being added to the atmosphere through burning of fuel but as the forests disappear ,less carbon dioxide is being removeed from the armosphere by plants. 因此,不仅是增加到大气的更多二氧化碳通过烧燃料,但是,当森林消失,较少二氧化碳是从armosphere removeed由...
Plants convert carbon dioxide into sugar and oxygen in the presence of sunlight. Plants store their sugar in the form of starch, which is used for growth and maintenance. Another essential factor necessary for plants to grow is soil. Air, water, sunlight, soil and warmth are the five things...
