Question

Explain levels of Biodiversity.​

Answer 1

$\sf{\pink{\underline{\underline{Levels\:Of\:Biodiversity}}}}$

Biodiversity exists not only other species levels but at all levels of biological organisations ranging from macromolecules within the cells do biotic community in a large area .

The Tom biodiversity was popularised by the sociobiologist Edward Wilson.

To describe the combined diversity at all the levels of biological organisation with three levels of biodiversity are.

1. Genetic diversity
2. Species diversity
3. Ecological diversity

$\sf{\green{\underline{Genetic\:Diversity}}}$

• It if the diversity of Genes within a species.
• A single species may show high diversity at the genetic level over its distributional range.
• Rauwolfia Vomitoria a medicinal plant growing in the Himalayan ranges shows great genetic variation which might be in terms of potency and concentration of the active chemical.
• India has more than 50,000 different strains of rice and 1000 varieties of mangoes.
• Genetic diversity increases with environmental variability and is advantageous for its survival.

$\sf{\red{\underline{Species \:Diversity}}}$

• It is the diversity at the special level .

Ex:- Amphibian diversity in the western ghats is greater than that of the Eastern Ghats.

$\sf{\blue{\underline{Ecological\:Diversity}}}$

• Diversity at a higher level of organisation .

Ex:- At the ecosystem level is called "Ecological diversity.

The other three indices of Ecological diversity are..

1. Alpha diversity is measured by counting the number of taxa.
2. Beta diversity is the species diversity between two adjacent ecosystems and is obtained by comparing the number of taxa.
3. Gamma diversity is the measure of the overall diversity for different ecosystem within Anika logical region.

Other attributes of biodiversity:-

• A species unique to a give area is called Endemic species.
• Pattern of biodiversity depends on factors such as Latitude and species area relation ship.
