The Cycling of Matter Why Learn About This? Most minerals essential for life cycle between living things and the atmosphere or the ground Atmosphere—gases surrounding Earth Biosphere—living ‘layer’ of Earth Lithosphere—soil/rock layer of Earth Hydrosphere—water parts of Earth Earth is a “clo...
A. Solid matter B. Liquid matter C. Gaseous matter D. All of the above 相关知识点: 试题来源: 解析 D。解析:在生态系统中,物质循环包括固态物质(如土壤中的矿物质)、液态物质(如水)和气态物质(如二氧化碳等气体)的循环,它们共同构成了物质循环的整体,所以A、B、C单独都不全面,D正确。反馈...
Which of the following is an important component of matter cycling in an ecosystem? A. Oxygen cycle B. Only carbon cycle C. Only nitrogen cycle D. Only phosphorus cycle 相关知识点: 试题来源: 解析 A。解析:在生态系统中,氧气循环是物质循环的一个重要组成部分,而不仅仅只有碳循环、氮循环或者磷...

The origin of the local interstellar matter, especially the hot component, is studied. The bulk of the local interstellar space is occupied with hot low-density matter, which is similar to the gas heated by the shock front of the supernova remnant. We investigate the model that our Sun is...

People in Amsterdam have been enjoying the benefits of cycling for years. 2. 阿姆斯特丹是个骑自行车的好城市,因为它很平坦,所以骑自行车很方便。 Amsterdam is a good city for cycling because it's flat and therefore convenient for bikes. 3. 因为骑行很方便,骑自行车在阿姆斯特丹非常受欢迎惊人的数据...
900 m. The cycling of carbon and associated tracers in the ocean is based on a size-structured plankton ecosystem model with a single (phosphate) nutrient42,43, and adopts an Arrhenius-type temperature-dependent scheme for the remineralization of organic matter exported to the ocean interior44...
Here we assess LOAC carbon cycling before the industrial period and perturbed by direct human interventions, including climate change. In our view of the global carbon cycle, the traditional ‘long-range loop’, which carries carbon from terrestrial ecosystems to the open ocean through rivers, is ...
