A
Alpha diversity

B
Beta diversity

C
Gamma diversity

D
Ecosystem diversity

Solution

Alpha diversity refers to the average species diversity of a habitat. Beta diversity is the diversity species between two habitats or regions and is given by the ratio between local (alpha species diversity) and regional species diversity. It is also known as the regional species diversity. Gamma diversity is the total diversity of a landscape.
So, the correct option is 'Beta diversity'.
Question 2
1 / -0

India is among $$12$$ megadiversity countries of world, due its percentage contribution in global species diversity, that is:-

A
$$1.8 \%$$

B
$$2.4 \%$$

C
$$8.1 \%$$

D
$$4.2 \%$$
Solution
Megadiversity refers to the diversity in various life forms. India is one of the megadiverse countries where diversity of global species is found. There are 4 biodiversity hotspots (the area where large species diversity is present) in India, they are:
Himalaya
Indo-Burma
Sundaland
The Western Ghats and Sri Lanka
In India, the total area under biodiversity hotspot is about 2.4 % and its contribution to global species diversity is about 7 - 8.5 %.
So, the correct option is '8.1%'.
