What do you mean by biodiversity?

Answer 1

Biodiversity - The variety of plants and animals and other living things in a particular area or region. Biodiversity is important because plant and animal species interact and depend upon one another for food, shelter, oxygen, and soil enrichment.

Biodiversity has no single standard definition. The most straightforward definition is "variation of life at all levels of biological organization"[3]. A second definition holds that biodiversity is a measure of the relative diversity among organisms present in different ecosystems. "Diversity" in this definition includes diversity within a species and among species, and comparative diversity among ecosystems.

A third definition that is often used by ecologists is the "totality of genes, species, and ecosystems of a region". An advantage of this definition is that it seems to describe most circumstances and present a unified view of the traditional three levels at which biodiversity has been identified:

genetic diversity - diversity of genes within a species. There is a genetic variability among the populations and the individuals of the same species. (See also population genetics.)
species diversity - diversity among species in an ecosystem. "Biodiversity hotspots" are excellent examples of species diversity.
ecosystem diversity - diversity at a higher level of organization, the ecosystem. To do with the variety of ecosystems on Earth.
This third definition, which conforms to the traditional five organization layers in biology, provides additional justification for multilevel approaches.

The 1992 United Nations Earth Summit in Rio de Janeiro defined "biodiversity" as "the variability among living organisms from all sources, including, 'inter alia', terrestrial, marine, and other aquatic ecosystems, and the ecological complexes of which they are part: this includes diversity within species, between species and of ecosystems".

This is, in fact, the closest thing to a single legally accepted definition of biodiversity, since it is the definition adopted by the United Nations Convention on Biological Diversity. The parties to this convention include all the countries on Earth, with the exception of Andorra, Brunei Darussalam, the Holy See, Iraq, Somalia, Timor-Leste, and the United States of America.

If the gene is the fundamental unit of natural selection, according to E. O. Wilson, the real biodiversity is the genetic diversity. For geneticists, biodiversity is the diversity of genes and organisms. They study processes such as mutations, gene exchanges, and genome dynamics that occur at the DNA level and generate evolution.

For biologists, biodiversity is the gamut of organisms and species and their interactions. Organisms appear and become extinct; sites are colonized and some species develop social organizations to improve their varied strategies of reproduction.

For ecologists, biodiversity is also the diversity of durable interactions among species. It not only applies to species, but also to their immediate environment (biotope) and their larger ecoregion. In each ecosystem, living organisms are part of a whole, interacting with not only other organisms, but also with the air, water, and soil that surround them.

Answer 4

The variety of plants and animals and other living things in a particular area or region. Biodiversity is important because plant and animal species interact and depend upon one another for food, shelter, oxygen, and soil enrichment.

Also
Biological diversity is the variety and variability among living organisms and the ecological complexes in which they occur.

And
Biodiversity is the variety of all living things; the different plants, animals and micro organisms, the genetic information they contain and the ecosystems they form.

RE:
What do you mean by biodiversity?

Answer 6

biodiversity is biological diversity in environment as indicated by numbers of different species of plants n animals

Answer 7

biodiversity means the variety of living things in one area...
the higher biodiversity, the more species of animals and plants are in that area..

the variety of species living in a defined area. thats the most concise i think i can make biodiversity for you :) (the 'defined area' could be an area of any size, like your garden, the nearest wild life park, madagascar or even the pacific ocean)

Answer 9

bio means life and diversity means many; so it means "many life" in an ecosystem. take for instance a plane ole creek (some call it a stream) there are fish, tadpoles, crawfish (we call the crawldads), snakes, frogs, lizards, bugs, spiders, turtles, ect, ect, ect.

Answer 10

it means that life species of multiple kinds exist together in one environment
