文學等多項科學,可以說它集合了所有與地球和生命有關的科學。
概念提出
生物圈的概念、要領是由奧地利地質學家休斯(E.Suess)在1875年*提出的,是指地球上有生命活動的領域及其居住環境的整體。它包括海平面以上約10000米至生物圈的要領,是指地球上有生命活動的領域及其居住環境的整體,下11000米處,其中包括大氣圈的下層,巖石圈的上層,整個土壤圈和水圈。但絕大多數生物通常生存于地球陸地之上和海洋表面之下各約100 m厚的范圍內,如果把地球看作一個足球大小,那么生物圈就比一張紙還要薄。
組成部分
生物圈主要由生命物質、生物生成性物質和生物惰性物質三部分組成。生命物質又稱活質,是生物有機體的總和;生物生成性物質是由生命物質所組成的有機礦物質相互作用的生成物,如煤、石油、泥炭和土壤腐殖質等;生物惰性物質是指大氣低層的氣體、沉積巖、粘土礦物和水。
存在條件
由此可見,生物圈是一個復雜的、性的開放系統,是一個生命物質與非生命物質的自我調節系統。它的形成是生物界與水圈、大氣圈及巖石圈(土圈)長期相互作用的結果,生物圈存在的基本條件是:
*、必須獲得來自太陽的充足光能。因一切生命活動都需要能量,而其基本來源是太陽能,綠色植物吸收太陽能合成有機物而進入生物循環。
第二、要存在可被生物利用的大量液態水。幾乎所有的生物全都含有大量水分,沒有水就沒有生命。
第三、生物圈內要有適宜生命活動的溫度條件,在此溫度變化范圍內的物質存在氣態、液態和固態三種變化。
第四,提供生命物質所需的各種營養元素,包括O2、CO2、N、C、K、Ca、Fe、S(氧氣 、二氧化碳、氮、碳元素、鉀元素、鈣元素、鐵元素、硫元素)等,它們是生命物質的組成或中介。
總之,地球上有生命存在的地方均屬生物圈。生物圈的要領是由奧地利地質學家休斯(E.Suess)在1875年*提出的,是指地球上有生命活動的領域及其居住環境的整體。生物的生命活動促進了能量流動和物質循環,并引起生物的生命活動發生變化。生物要從環境中取得必需的能量和物質,就得適應環境,環境發生了變化,又反過來推動生物的適應性,這種反作用促進了整個生物界持續不斷的變化。生物圈里繁衍著各種各樣的生命,為了獲得足夠的能量和營養物質以支持生命活動,在這些生物之間,存在著吃與被吃的關系。“大魚吃小魚,小魚吃蝦米”,這句俗語就體現了這樣一種簡單的關系。但是,要維持整個龐大的生物圈的生命活動,這么簡單的關系顯然是不行的。生物圈有自我調節的能力。生物圈是一個統一的整體。
Literature and many other sciences, it can be said that it brings together all the earth and life-related science.
Concept raised
The concept of the biosphere, which was first proposed by the Austrian geologist E.Suess in 1875, refers to the area of ??life on Earth and the whole of its living environment. It includes the essentials of about 10,000 meters above sea level to the biosphere. It refers to the area of ??living activity on Earth and its living environment at a total depth of 11000 meters, including the lower atmosphere, the upper lithosphere, the entire pedosphere and Hydrosphere. However, the vast majority of organisms usually live above and above the surface of the Earth about 100 m thick. If the Earth is viewed as a football, then the biosphere is thinner than a piece of paper.
component
The biosphere is mainly composed of three parts: living matter, bio-generative substance and bio-inert substance. Living matter, also known as living matter, is the sum of living organisms; biogenic matter is a product of the interaction of organic minerals composed of living matter such as coal, oil, peat and soil humus, etc. Bio-inert material refers to the atmosphere Lower gas, sedimentary rocks, clay minerals and water.
There are conditions
Thus, the biosphere is a complex and global open system, which is a self-regulating system of living and non-living matter. Its formation is the result of the long-term interaction between the biological world and the hydrosphere, the atmosphere and the lithosphere (soil circle). The basic conditions for the existence of the biosphere are:
First, there must be sufficient light energy from the sun. Because all life activities require energy, and its basic source of solar energy, green plants absorb solar energy into the organic synthesis into the biological cycle.
Second, there is a lot of liquid water that can be bioavailable. Almost all of the creatures contain a lot of water, no life without water.
Third, the biosphere should have suitable temperature conditions for life activities. There are three kinds of changes in the temperature range: gaseous, liquid and solid.
Fourth, to provide all kinds of nutrients needed by living matter, including O2, CO2, N, C, K, Ca, Fe and S (oxygen, carbon dioxide, nitrogen, carbon, potassium, calcium, Elements), etc., which are the composition or intermediary of living matter.
In short, there are biosphere where life exists on earth. The essentials of the biosphere, first proposed by the Austrian geologist E.Suess in 1875, refer to the area of ??life on Earth and its living environment as a whole. Biological life activities promote the flow of energy and material circulation, and cause changes in biological life activities. Creatures need to get the necessary energy and material from the environment, have to adapt to the environment, the environment has changed, and in turn promote biological adaptability, this reaction has contributed to the continuous changes in the entire biological world. There are various kinds of life in the biosphere. In order to get enough energy and nutrients to support life activities, there is a relationship between eating and being eaten. "Big fish eat fish, fish eat shrimp," This saying proves such a simple relationship. However, in order to maintain the life activities of the entire vast biosphere, such a simple relationship obviously does not work. Biosphere has self-regulating ability. Biosphere is a unified whole.
