Mega Diverse Countries and Bio Diversity Hosspot

 The criteria for a mega-diverse countries is classified based on two factors : (1) Have at least 5,000 endemic plants and (2) Have a marine ecosystem within the borders.

India is one of the recognized mega-diverse countries of the world, harbouring nearly 7-8% of the recorded species of the world, and representing 4 of the 34 globally identified biodiversity hotspots (Himalaya, Indo-Burma, Western Ghats and Sri Lanka, Sundaland).

To qualify as a biodiversity hotspot, a region must meet two strict criteria:

It must have at least 1,500 vascular plants as endemics — which is to say, it must have a high percentage of plant life found nowhere else on the planet. ...

It must have 30% or less of its original natural vegetation.

Lionesses also live within such established territory and mate with the dominant male controlling that territory.  While male lions protect females and try expand their territory, females hunt and feed cubs. The dominant male lions also mostly rely on females for hunting though they ofte

Chief Requirements for Orographic Rainfall

  It occures when the saturated air mass comes across a mountain, it is forcefully lifted. With the expansion of rising air, eventually, the temperature falls, and the moisture gets condensed.  The principal characteristic of this type of rain is that the windward slopes get more rainfall. After giving rain on the windward side, when these winds reach the other slope, they drop away, and their temperature increases. Then their ability to take in moisture increases and hence, these leeward slopes remain dry and rainless. The region situated on the leeward side is known as the rain-shadow area. Movement of saturated air mass towards the hill slope. Forcefully upliftment
