Eventually, soil organic carbon can be lost back into the atmosphere in the form of carbon dioxide, become material of the soil that is eroded, or be dissolved in the form of organic carbon and runoff into the oceans and rivers. This is called the carbon cycle which decides the soil ...
Plants play a crucial role in the carbon cycle. Which of the following best describes how plants contribute to the carbon cycle? A. Plants release only carbon dioxide during respiration B. Plants take in carbon dioxide during photosynthesis and release it during respiration C. Plants take in ...
This paper examines the various soil, plant, and animal processes that generate acid (protons; H+ ions) during the cycling of carbon (C), nitrogen (N) and sulfur (S). These processes include: plant-induced processes (viz., carbon assimilation, and uptake and assimilation of N and S); ...
A. release a large amount of carbon dioxide B. absorb and store carbon dioxide C. have no effect on carbon dioxide D. only produce oxygen 相关知识点: 试题来源: 解析 B。解析:森林在全球碳循环中起着至关重要的作用,主要是因为树木通过光合作用吸收并储存二氧化碳,而不是释放大量二氧化碳,所以A错误...
This uncertainty in the future trajectory of atmospheric CO 2 that comes from incomplete understanding of the marine carbonate cycle is cause for concern. 展开 关键词: Earth system carbon cycle carbonate calcifiers ocean chemistry CO 2 fossil fuel ...
Subterranean ecosystems play an active role in the global carbon cycle, yet only a few studies using indirect methods have focused on the role of the cave microbiota in this critical cycle. Here we present pioneering research based on in situ real-time monitoring of CO2 and CH4 diffusive fluxes...
