To better organize out content, we have unpublished this concept. Biodiversity is not evenly distributed, rather it varies greatly across the globe as well as within regions. Draw a neatly labeled diagram of chloroplast found in leaf, and its role in photosynthesis? As all the organisms in an ecosystem are interdependent, removing just one species can prevent the ecosystem from operating normally. Much has been published on the subject since its first appearance at the National Forum on BioDiversity in September, 1986, the proceedings of which became the best-seller, BioDiversity. It is usually described at three levels: genetic, species, and ecosystem. What are your observations in combustion of sugar activity? Through proper education and awareness, the peoples conscience against such practices must be raised. Humans are also attracted towards the biologically rich regions and nobody likes to live or visit a barren place. How is the biodiversity of an ecosystem measured? Two of the worlds 25 biodiversity hotspots are found in India. Habitat loss is the single greatest threat to biodiversity on Earth today and in fact it is the second largest threat to our existence on this planet next to Climate Change. A diverse ecosystem is more productive and can withstand environmental stress.

Earth is a unique planet as it supports life and possesses a vast diversity amongst the organisms that exist on it. Methods of measuring and valuing biodiversity. The term biodiversity was coined by Walter G Rosen in 1986, and the literal meaning of the word is biological diversity. A species' potential to adapt to changing environments or new diseases depends on this genetic diversity. The count of species in a region is known as species richness. Genetic diversity pertains to the range of diversity in the genetic resources of the organisms. This concept of biological resources management probably explains most fears of resource disappearance related to erosion of . biodiversity - definition the number and variety of plants, animals and other organisms that exist in an ecosystem is known as biodiversity it is a measure of the variety of organisms present in different ecosystems the richness of biodiversity depends on the climatic conditions and area of the region ' biodiversity is the result of 3.5 billion Similarly, all our domesticated animals came from wild-living ancestral species.

Each species is adapted to live in specific environment, from mountain peaks to the depth of seas, from polar ice caps to tropical rain forests and deserts. Though the study of environment and ecology is quite old, the term biodiversity has been introduced by Walter Rosen in 1986. Genetic diversity is the variety of genes within a 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. Community-Level Biodiversity: An Inquiry into the Ecological and Cultural Background and Practical Consequences of Opposing Concepts 6.Ethics of Nature and Biodiversity 7.

Since the indigenous people always protect the forests for their own benefit, the Government should formulate plans to involve such people for environmental protection. BIODIVERSITY Healthy ecosystems are vital to life. Social benefits: Recreation and tourism, cultural value and education and research. Biodiversity, or biological diversity, is a term that refers to the number of genes, species, individual organisms within a given species, and biological communities within a defined geographic area, ranging from the smallest ecosystem to . The genes present in the organisms can form infinite number of combinations that causes genetic variability. Biodiversity is the heterogeneity which exists at different levels of biological organisations in our biosphere.

For example, a significant number of such non-timber forest products as soft broom grass and cane come under this category. While biodiversity has been accepted as a core goal of modern conservation science, there is some scepticism in the philosophical literature toward the utility of this concept. Although the concept of biodiversity did not become a vital component of biology and political science until nearly 40 years after Aldo Leopold's death in 1948, Leopold - often considered the father of modern ecology - would have likely found the term an appropriate description of his "cogs and wheels." Decisions humans make that influence biodiversity affect the well-being of themselves and others. the number of species within a community. It refers to genetic variation, ecosystem variation, species variation (number of species) within an area, biome or planet. In the recent decades, a new science named biotechnology has emerged. Biodiversity is the variety of different forms of life on earth, including the different plants, animals, micro-organisms, the genes they contain and the ecosystem they form. 3 What are characteristics of biodiversity? 19.1). Climate change is predicted to be a significant cause of extinction in the coming century. This is the change in the composition of the species with reference to the changes in the environment.

This depends on the interaction between the biotic and abiotic factors and also takes into account immigration from other locations. Biodiversity represents the original stock from which new varieties are being developed. Put your understanding of this concept to test by answering a few MCQs. Economic Importance. Maintenance of ecological balance, conservation of natural resources and prevention of soil erosion may be considered as the examples of indirect use of biodiversity. It is the most complex and important feature of our planet.

Biological diversity or Biodiversity is defined as the variety and variability among the living organisms and the ecological complexes in which they occur. Since the 16th century, human activity has impacted nature in practically every part of the world, wild plants and animals are at risk of extinctio Ecosystems that host the most biodiversity tend to have ideal environmental conditions for plant growth, like the warm and wet climate of tropical regions. Thus, we find that each human, who is representative of the same species, i.e. However, diversity is depleting at a drastic rate and various programmes on biodiversity conservation are being launched to conserve nature.
