India is also very rich in agro diversity.
NATURAL VEGETATION AND WILDLIFE
Natural vegetation refers to a plant community which has grown naturally without human aid & has been left undistributed by humans for a long time.
This is termed as a virgin vegetation.
Thus, cultivated crops and fruits, orchards form part of vegetation but not natural vegetation
Land is among the most important natural resources. It covers only about thirty per cent of the total area of the earth’s surface and all parts of this small percentage are not habitable.
The uneven distribution of population in different parts of the world is mainly due to varied characteristics of land and climate.
Land affects the natural vegetation directly and indirectly. The fertile level is generally devoted to agriculture. The undulating and rough terrains are areas where grassland and woodlands develop and give shelter to a variety of wild life.
The thin layer of grainy substance covering the surface of the earth is called soil. It is closely linked to land. Landforms determine the type of soil. Soil is made up of organic matter, minerals and weathered rocks found on the earth.
The soils also vary over space. Different types of soils provide basis for different types of vegetation. The sandy soils of the desert support cactus and thorny bushes while wet, marshy, deltaic soils support mangroves and deltaic vegetation. The hill slopes with some depth of soil have conical trees.
Temperature is a physical property of matter that quantitatively expresses the common notions of hot and cold. Objects of low temperature are cold, while various degrees of higher temperatures are referred to as warm or hot. When a heat transfer path between them is open, heat spontaneously flows from bodies of a higher temperature to bodies of lower temperature. The character and extent of vegetation are mainly determined by temperature along with humidity in the air, precipitation and soil.
