These terms all refer to the idea of living variation, from genes and traits, to species, and to ecosystems.
The term biodiversity was coined as a contraction of biological diversity by E. Wilson in Biodiversity may be defined as the variety and variability of living organisms and the ecological complexes in which they exist. In other words, biodiversity is the occurrence of different types of ecosystems, different species of organisms with the whole range of their variants and genes adapted to different climates, environments along with their interactions and processes. Biodiversity includes the genetic variability for which different varieties of spices have appeared in the course of evolution and diversity of life forms such as plants, animal microbes, etc. The diversity may be interspecific within species and interspecific in between the species but these are well supported by ecosystem.
Biodiversity , also called biological diversity , the variety of life found in a place on Earth or, often, the total variety of life on Earth. A common measure of this variety, called species richness , is the count of species in an area. Colombia and Kenya, for example, each have more than 1, breeding species of birds, whereas the forests of Great Britain and of eastern North America are home to fewer than A coral reef off northern Australia may have species of fish, while the rocky shoreline of Japan may be home to only species. Such numbers capture some of the differences between places—the tropics, for example, have more biodiversity than temperate regions—but raw species count is not the only measure of diversity.
Biodiversity is the biological variety and variability of life on Earth. Biodiversity is typically a measure of variation at the genetic , species , and ecosystem level. Rapid environmental changes typically cause mass extinctions. The age of the Earth is about 4. There are microbial mat fossils found in 3.

Biodiversity is the sum of all the different species of animals, plants, fungi and microbial organisms living on Earth and the variety of habitats in which they live. Scientists estimate that more than 10 million different species inhabit Earth. Biodiversity underlies everything from food production to medical research. Humans use at least 40, species of plants and animals on a daily basis. Many people around the world still depend on wild species for some or all of their food, shelter and clothing. All our domesticated plants and animals came from wildliving ancestral species.
The living world is a complex combination of different levels of organisms. The key components of life are at one extreme and communities of species at the other extreme. The manifestations of all types of diversities are found at all these levels of organisms. Biodiversity is the shorter form of word biological diversity which means diversity in the biological world. Thus one can define biodiversity as the degree of variety in nature with regards to biological species. It is the variation of genes within the species. This results distinct population of one, even same species.
The number and variety of organisms found within a specified geographic region. The variability among living organisms on the earth, including the variability within and between species and within and between ecosystems. Biological diversity — or biodiversity — is the term given to the variety of life on Earth. It is the variety within and between all species of plants, animals and micro-organisms and the ecosystems within which they live and interact. Biodiversity comprises all the millions of different species that live on our planet, as well as the genetic differences within species.
Biodiversity, or Biological Diversity, is the sum of all the different species of plants, animals , fungi and microbial organisms that live on Earth , including the various ecosystems in which they live on. Biodiversity also includes the genetic information that these organisms contain. Therefore, on a smaller scale, you can use biodiversity to describe the variation in the genetic makeup of an organism. On a larger scale, you can use it to describe various types of ecosystems. Biodiversity plays an integral role in the way ecosystems work and in the benefits they provide.
Biodiversity, besides its ecological significance provides a socio-economic and monetary asset to the nation. Human society depends on biological resources, their diversity and the ecosystems that sustain them to provide essential goods and services.
- Подтирка для задницы. Беккер не шелохнулся. Что-то сказанное панком не давало ему покоя. Я прихожу сюда каждый вечер.
Сьюзан встретилась с ним взглядом и прикусила губу. - Ничего, - выдавила. Но это было не. Терминал Хейла ярко светился.
Специально для тебя, дорогая. Он стал ждать, когда его компьютер разогреется, и Сьюзан занервничала. Что, если Хейл захочет взглянуть на включенный монитор ТРАНСТЕКСТА. Вообще-то ему это ни к чему, но Сьюзан знала, что его не удовлетворит скороспелая ложь о диагностической программе, над которой машина бьется уже шестнадцать часов. Хейл потребует, чтобы ему сказали правду.
