factors for the growth of Natural Vegetation


DEFINITION OF VEGETATION:
“Vegetation of some sort or the other is the natural covering of the land surface of the Earth”.

Qno2. Explain the factors for the growth of Natural Vegetation? 

FACTOR FOR THE GROWTH OF NATURAL VEGETATION: 
Following are the factors for the growth of natural vegetation.

1. The amount of Heat (Temperature) 
2. The amount and distribution of precipitation (Rainfall, wind) 
3. The amount of light 
4. The character of soils

THE AMOUNT OF HEAT (TEMPERATURE):
The growth and type of vegetation at a particular place depends upon the climate and physical features, but temperature plays an important role. Thus in the equatorial region where temperature is high, dense forest are not found.

THE AMOUNT OF DISTRIBUTION OF PRECIPITATION (RAINFALL):
Next in importance to temperature are the amount and the seasonal distribution precipitation, either in the form of rain or snow. Thus, in areas of heavy rain dense forest seen and in intermediate rain grasslands and areas of meager rainfall desert vegetation can be seen.

THE AMOUNT OF DISTRIBUTION OF PRECIPITATION (WINDS):
The function of winds is to help the plants in transpiration i.e. getting rid of the excess moisture.

LIGHT: Light is the chief factor where by the plant manufacturers its food (sugar) from the green material in the leaves, become yellow and within the plant dies.

SOIL:

The moisture supply the roots of the plant is determined by the texture of soil. The effectiveness of precipitation is greatly influenced by soil structure.
