The number and variety of organisms found within a specified geographic region.

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

Biodiversity

These terms all refer to the idea of living variation, from genes and traits, to species, and to ecosystems. These events often are interpreted as the beginning of the biodiversity story, but this mids activity actually was both a nod to important past work, and a launching of something quite new, in ways not fully anticipated. This recognised the idea that living variation itself has current value, because it provides the opportunity for future benefits for humanity. The range of conceptual issues addressed are reflected in recent books on the philosophy of biodiversity, including What is Biodiversity? While the policy context for conservation of biodiversity has maintained a core focus on variety as reflected in the CBD and IPBES definitions , the more academic discussions are harder to pin down.

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

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.

What is Biodiversity?

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. It has been estimated that more than 50 million species of plants, animals and micro-organisms are existing in the world.

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.

The Definition

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.

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.

Biodiversity

Простите, что я так долго до вас добирался. - Мне даже не сказали, что вы придете. Беккер поспешил переменить тему: - У вас на голове огромная шишка. Больно.

 Я верю этим данным. Чутье подсказывает мне, что здесь все верно. Бринкерхофф нахмурился.

Такая работа была непростой, особенно для человека его комплекции. И они делают их все более и более миниатюрными, - подумал. Прикрыв глаза, давая им долгожданный отдых, он вдруг почувствовал, что кто-то тянет его за ногу. - Джабба. Вылезай скорее! - послышался женский голос.

Беккер посмотрел в другую сторону и увидел, что женщина, сидевшая рядом, уже ушла и весь ряд вплоть до центрального прохода пуст. Не может быть, что служба уже закончилась. Это невозможно.
