Such a harmonious structure is the outcome of a very long period of trial and error-the 5 billion years of biological evolution. The biological sector of the ecosphere-the biosphere is composed of living things that have survived this test because of their finely tuned adaptationto the ...
As these nations become more technological, they will consume more energy, deplete more natural resources, and create more waste products than the biosphere can absorb.小题1:The life-support system is composed of ___. A.air, water and land B.the earth, the sun and energy C.food, land...
The earth's biosphere (the surface layer of the planet and the surrounding atmosphere) provides the land, air, water, and energy necessary to sustain life. This life-support system is a complex, interdependent one in which energy from the sun is changed into food for humans. The entire syst...
Biosphere The biosphere is the global ecosystem, which is the zone of life on Earth. It is composed of three different parts, which are abiotic, biotic and energetic components. The biosphere is where life exists. Answer and Explanation: ...
This would appear to be a truly unique event, and highlights a key interaction between two levels of organization within the Biosphere, the genome and the proteome, in terms of entropy production. The Biosphere is seen as being composed of a series of self-organizing sub-groups, each ...
biosphere(生物圈):是地球上凡是出现并感受到生命活动影响的地区,是地球上最大的生态系统。 ecological pyramid(生态椎体或生态金字塔):是指生态系统中不同营养级的生物量、数量或能量的组成比例,通常用图解表示。 food chain(食物链):生产者所固定的能量和物质,通过一系列取食和被食的关系在生态系统中传递,各种生物...
Despite the apparent enormity of the number of species that inhabit the earth as a whole, local biopersity—the number of species found in any one habitat—fluctuates greatly as we cross the boundaries separating the ecosystems that make up the Earth’s biosphere. It reaches its highest levels...
biosphere, irregularly shaped envelope of the earth's air, water, and land encompassing the heights and depths at which living things exist. The biosphere is a closed and self-regulating system (see ecology), sustained by grand-scale cycles of energy and of materials—in particular, carbon, ox...
ais composed of all the regions of the earth that contain living things. This generally includes the top few meters of soil, the oceans and other bodies of water, and the lower ten kilometers of the atmosphere.Biosphere 包含生物由地球的所有地区的组成。 这一般包括顶面土壤少量米、海洋和其他水...
The increasing recognition of the lack of diversity and thus a reduced resilience of planet Earth as a symbiotic and self-regulating system - sustained by complex interactions across the Geosphere, Biosphere, and Anthroposphere - is essential to understand preconditions and processes leading to disease...
