which factor control the vegetation of a region
Answers
Answer:
Factors that affect natural vegetation of a place are:
- Land. Land affects the growth of natural vegetation as different kinds of vegetation grow on mountains, plateaus, plains and in deserts.
- Soil. Soil determines the growth of different types of vegetation.
- Temperature.
- Photoperiod.
- Precipitation.
Explanation:
Land affects the growth of natural vegetation as different kinds of vegetation grow on mountains, plateaus, plains and in deserts. For example, a variety of grasslands and woodlands develop on mountains and uneven terrains. Soil determines the growth of different types of vegetation. While mangrove forests grow on wet and marshy deltaic soils, cactus and thorny bushes grow on sandy soils. Temperature affects the growth of natural vegetation. Temperature affects humidity, precipitation and the type of soil. We find the growth of conical-shaped trees at higher altitudes. Photoperiod refers to the period of sunlight which an object or a tree receives. Sunlight varies at different places at different latitudes, different altitudes and in different seasons. Precipitation affects the growth of natural vegetation. Areas receiving high rainfall, such as the equatorial regions, experience rich growth of vegetation. Vegetation cover is sparse in regions such as hot and cold deserts which receive less than 25 cm of rainfall.

Answer: These include temperature, rainfall, insolation and winds. The most critical of these factors are temperature and rainfall and a proper balance must be maintained between the two for plants to grow well. An example, in cold lands,plants growth is impossible below 6°C no matter how heavy the rainfall is.
