The following table shows the population data $(A-D)$ of ten species $a$ to $j$. Study the table and answer the following question.

Area and Number of Habitats	Species and their numbers (in thousands)
	$a, b, c, d, e, f, g, h, i, j$
$A (11)$	$2.3, 1.2, 0.52, 6.0, -, 3.1, 1.1, 9.2, -, 10.3$
$B (11)$	$10.2, -, 0.62, -, 1.5, 3.0, -, 8.2, 1.1, 11.2$
$C (13)$	$11.3, 0.9, 0.48, 2.4, 1.4, 4.2, 0.8, 8.4, 2.2, 4.1$
$D (12)$	$3.2, 10.2, 11.1, 4.8, 0.4, 3.3, 0.8, 7.3, 11.3, 2.1$

Which area among $A$ to $D$ shows the highest species diversity?

Where is the greatest genetic diversity found in agricultural crops?

Assertion : Diversity observed in the entire geographical area is called gamma diversity.
Reason : Biodiversity decreases from high altitude to low altitude.

Initially $A$ biodiversity hot spots were identified but subsequently nine more have been added to the list,bringing the total number of biodiversity hot spots in the world to $B$. These hot spots are the regions of accelerated habitat loss. Three of these hot spots—Western Ghats and Sri Lanka,Indo-Burma,and Himalaya—cover our country's exceptionally high biodiversity regions. Although all the biodiversity hot spots put together cover less than $C$ $\%$ of the earth's land area,the number of species they collectively harbour is extremely high,and the strict protection of these hot spots could reduce the ongoing mass extinctions by almost $D$ $\%$. $A, B, C$ and $D$ in the paragraph refer to:

Which of the following statements describes a stable community?

Which of the following taxon shows maximum species diversity?
