3 levels of biodiversity and its meaning

Though the species and organisms in each level may vary from each other, they too form important interactions that have bigger ripple effects on other species and organisms. i֜kv�J�6�w�~*�:ʵz��׹��.�&���yl�-2�8vd�k��84e �������?� 0000002792 00000 n Biodiversity can be considered in THREE levels (1). Species Diversity. Out of an estimation 30 million species on earth, only one-sixth has been identified and authenticated in the past 200 years. Biodiversity encompasses the variety of life, at all levels. Or the Great Barrier Reef. Keystone species would include pollinators, top predators and the decomposer organisms and so-forth.

Cultural services such as recreational, aesthetic and spiritual benefits 4. The challenges are at least two-fold; to meet farmers’ needs for wide genetic diversity whether through enhanced access to local varieties or newly introduced genetic resources; and to find strategies for linking longer-term conservation goals with immediate product needs. On the wider scale, biodiversity includes variations in the biological communities in which species live, the ecosystem in which communities exist, and the interactions among these levels. Again it indirectly influences the climatic factors, soil nature, chemistry of air etc. 0000496386 00000 n 3. Genetic diversity: Genetic variation within species, both among individuals within single population and among geographically separated populations (2). 0000013352 00000 n Thus, it refers to the variety of species within a region.

The biodiversity we see today is a result of 3.5 billion years of evolution. Biodiversity is an essential part of the solution to climate change. All forms of life from microbes to plants to humans contain genes. The loss of biodiversity could adversely affect our environment as the balance is lost and the natural food web is disturbed.

No feature of Earth is more complex, dynamic, and varied than the layer of living organisms that occupy its surfaces and its seas, and no feature is experiencing more dramatic change at the hands of humans than this extraordinary, singularly unique feature of Earth. 0000496673 00000 n A productive and stable agriculture requires genetic diversity on the farm. Genetic diversity is all the different genes contained in all the living species, including individual plants, animals, fungi, and microorganisms. Protecting the Gir Habitat, for instance, has saved the Asiatic Lion. 0000458476 00000 n The following is a list of some of the benefits, or services, of biodiversity: 1. A great deal of work needs to be done on the conservation of genetic diversity within wild species in India. The three types of Biodiversity is Genetic Diversity, Species Diversity, and Ecosystem Diversity. 0000440362 00000 n Members of a species share genes. 0000533915 00000 n Content Guidelines Dogs, Cats etc.). +ڽGjF2���/���|�BK�7���@�oqE0�`Em�����X`�U�1'T]�R2:6��(���-�>��й?W�*X����۫-�[�(�U�9VIY�O�o�t�b��B����X�)�E���^L��Ϳ`0��wв��I2�AX�7�z�H�"�j>�QSd�7H��w�Xs�̿��M��.�;v2�X �Ng��3��-,���Z�����0�YߧH���6toX�)n�v�f �?�Rƅ��HzN&^��Ѽ��O��� 2. 1997), documents the rapidrise of the term “biodiversity” in importance and influence. New genetic variation, which arises by gene and chromosome mutation in individuals and in sexually reproducing organisms, is spread in the population by a recombination of genetic material during cell division preceding sexual reproduction. 0000014187 00000 n Biodiversity is the foundation of ecosystem services to which human well-being is intimately linked. that are the abiotic elements of an ecosystem. 0000495347 00000 n Biodiversity at its most basic level includes the full range of species on earth from micro- orgnisms such as viruses, bacteria through the multicellular kingdom of plants, animals and fungi. 0000496054 00000 n 0000006155 00000 n 0000468459 00000 n The variety of life on Earth, its biological diversity is commonly referred to as biodiversity. 0000004069 00000 n Here are some other ways to look at biodiversity in a rainforest. 0000010985 00000 n 0000004013 00000 n ‘Valuing a loss of biodiversity is more difficult because markets for its preservation are either missing or incomplete.’ ‘The net effect of slashing and burning on biodiversity is difficult to evaluate.’ ‘Australia, like all countries on earth is defined by its biodiversity.’ 0000003972 00000 n 0000011743 00000 n 0000495950 00000 n Scientists have named three different levels of biodiversity: genetic diversity, species diversity, and ecosystem diversity. In the living world, interdependence and interaction between organisms and their environment are a very common practice to assert one’s existence on this planet. 1. Terrestrial biodiversity is usually greater near the equator, which is the result of the warm climate and high primary productivity. 0000008095 00000 n These species will also look more similar. 0000545893 00000 n The replacement of numerous locally adapted varieties with a few high yielding strains in the large contiguous areas presents the danger of the spread of serious diseases capable of wiping out the entire crop, as happened prior to the Bengal rice famine in 1942. 0000511356 00000 n All species on Earth are somewhat related through genetic connections. Bio is a Greek word.

On a smaller scale, we can describe the biodiversity of a local forest, park or pond. Differences between individual organisms have two causes: variation in the genetic material which all organisms possess and which is passed on from generation to generation; and variation caused by environmental influence on each individual organism. 0000002640 00000 n 0000008073 00000 n 0000468804 00000 n Biodiversity refers to the variety of living species on Earth, including plants, animals, bacteria, and fungi. 0000007176 00000 n Ecosystem diversity could be best understood if one studies the communities in various ecological niches within the given ecosystem.

A common measure of this variety, called species richness, is the count of species in an area. 0000008817 00000 n 0000416398 00000 n These three levels work together to create the complexity of life on Earth. It occurs within a species as well as between species. In general, biodiversity is considered at three (progressively-wider) levels: genetic diversity, species diversity, and ecosystem diversity. reflects the entire range of evolutionary and ecological adaptations of species to particular environments. 0000468355 00000 n It also refersto the variation in genetic information betweenspecies as well as the variations between individualsof the same … ��T?�Q�"��'��]���� Brown hair, Blue eyes etc. On the other hand, nature always tries to remain in homeostatic state and various life forms help to maintain this equilibrium.
