Biodiversity Is a Crucial Part of the Earth's Natural Captial

Biological diversity,or biodiversity,is the diversity of the earth's species,the genes they contain,the ecosystems in which they live,and the ecosystem processes of energy flow and nutrient cycling that sustain all life (Figure 3-12).
Biodiversity is a vital renewable resource (Concept 3-4A).Figure 3-13 (P.50) shows just two of the great variety of species found in tropical forests.Also,see photo 3, p. vii.Populations of these and countless other species in other ecosystems contain the variety of genes that make the genetic component of biodiversity.Genetic diversity provides a variety of genes that enable life on the earth to adapt to and survive dramatic environmental changes.

Functional Diversity
The biological and chemical processes such as energy flow and matter recycling needed for the survival of species,communities,and ecosystems.

Ecological Diversity
The variety of terrestrial and aquatic ecosystems found in an area or on the earth.

Genetic Diversity
The variety of genetic material within a species or a population.

Species Diversity
The number and abundance of species present in different communities.

3-4A
The biodiversity found in the earth's genes,species,ecosystems,and ecosystem processes is vital to sustaining life on the earth.

Natural capital:the major components oif the earth's biodiversity-one of the earth's most important renewable resources.See an animation based on this figure at ThomsonNow.

species diverity:two species found in tropical forests are part of the earth's biodiversity.On the right is an endangered white ukari in a Brazilian tropical forest.On the left is the world's largest flower,the flesh flower (Rafflesia) growing in a tropical rain forest of West Sumatra,Indonesia.The flower of this leafless plant can be as large 1 meter (4.3feet) in diameter and weigh 7 kilograms (15pounds).The plant gives off a smell like rotting meat,presumably to attract flies and beetles that pollinate the flower.After blossoming once a year for a few weeks,the blood red flower dissolves into a slimy black mass.


生物多樣性是一個關鍵部分,地球的自然資本

生物多樣性,或生物多樣性,多樣性是地球的物種,它們包含的基因,生態系統,他們在生活和生態系統過程的能量流和養分循環,維持所有生命(圖3-12 ) 。
生物多樣性是一個重要的可再生資源(概念3 - 4A型) 。圖3月13日(臨50 ) ,表明兩個偉大的各種物種於熱帶森林.見照片3 這些以及無數其他物種的其他生態系統包含的各種基因,使遺傳多樣性的組成部分生物多樣性.遺傳多樣性提供了各種各樣的基因,使生活在地球上,以適應生存環境變化顯著。

功能多樣性
生物和化學過程,如能量流動和物質循環的生存需要的物種,群落和生態系統。

生態多樣性
各種各樣的陸地和水生生態系統發現某一地區或在地球上。

遺傳多樣性
品種的遺傳物質在一個物種或一個人口。

物種多樣性
的數量和豐富的物種在不同的社區。

3 - 4A型
生物多樣性在地球的基因,物種,生態系統和生態系統過程是至關重要的維持生命的地球。

物種多樣性:兩個物種的發現在熱帶森林的一部分,地球生物多樣性.權利是一種瀕危的白ukari在巴西熱帶森林.在左邊是世界上最大的花 ,肉花(大王花)越來越多的熱帶雨林森林的西蘇門答臘, 印度尼西亞.這花本葉植物可大1米(四點三英尺)的直徑和重量七千克(十五磅) 。工廠發出的氣味像腐爛的肉,大概是為了吸引蒼蠅和甲蟲的開花授粉的花.之後每年一次的幾個星期之內,血紅色的花溶成一個泥濘的黑人群眾。
