The ecological factors that affect the growth of plants and determine the nature of plant communities are divided into three types.
The three types of ecological factors are: (1) Climatic factors which include rainfall, atmospheric humidity, wind, atmospheric gases, temperature and light (2) Physiographic factors which include altitude, effect of steepness and sunlight on vegetation and direction of slopes (3) Biotic factors which include interrelationship between different plants of a particular area, interrelationship between plants and animals occupying the same area and interrelationship between soil microorganisms and plants.
I. Climatic Factors:
The important climatic factors of a region are rainfall, atmospheric humidity, wind, temperature, and light. Of these climatic factors each one individually contributes to the general and overall effect of climate by influencing the life processes of plants which constitute the vegetation.
