support. Different type of soil provide basis to differernt
type of vegetation.
6. climate
Temprature
The vegetation is not only determined by the temprature but it
also determined by the humidity in air,soil and precipitation.The
fall in temprature affect the vegetation and its growth and
change it from tropical to sub-tropical to temprature and Alpine
vegetation.
Precipitation
