AIIMSAIIMS 1996

Solution:

Alpine tundra is the highest altitudinal biome which occurs near the top of very high mountains having permanent snow i.e. at the height to approximate 3500 metres, e.g. in Himalayas "alpine tundra" vegetation is found. It is a treeless region and lies above the timber line. Trees of lower region becomes tiny shrubs in this area (e.g. Rhododendron, Juniperus, Abies). Other constituents of alpine tundra are lichens, mosses, grasses, herbs and small shrubs like Artemesia, Arenaria, Primula and Anemone.
