What are the factors affecting flora and fauna of a region????? explain brieflyplz answer fast
Answers
Land: Land directly and indirectly affects the natural vegetation. Nature of land influences the type of vegetation. If the land is level and fertile, it is mainly used for farming. If the land is uneven then grassland and woodlands develop over it.
Soil: Different types of soil are fit for different types of vegetation. For example; sandy soil is fit for cactus and thorny bushes, while wet and marshy soil is fit for mangrove vegetation.
CLIMATE
Temperature and Humidity: Temperature and humidity are the main factors which determine the character and extent of vegetation. An area with high temperature and high humidity supports evergreen forest, while an area with high temperature and low humidity supports thorny bushes.
Photoperiod (Sunlight): The duration of sunlight is called photoperiod. Photoperiod depends on latitude, altitude, season and duration of the day. Trees grow faster in summer because of longer photoperiod.
Precipitation: If an area gets heavy rainfall, it is suitable for the growth of dense vegetation. On the other hand, an area with scanty rainfall is suitable for thorny bushes.
Ecosystem: All the plants and animals in an area are interdependent on each other. The plants and animals; alongwith their physical environment make the ecosystem. A very large ecosystem is called a biome. Biomes are identified on the basis of plants.

▶The factor which affect the Flora & Fauna of any region are:-
===========================⤵
❖ A wide range of fauna and flora persists in a country and this huge diversity is due to many factors like Relief, Climate & ecosystem etc.
❖ Under the relief category land and soil exists while under the climate, temperature, sunlight & precipitation exist.
❖ The extent of vegetation is determined by temperature and other elements like humidity in air, precipitation, and soil.
❖ Humans also form a part of the ecosystem and they utilise the vegetation and wildlife forms.
❖ Different types of soils provide basis for different forms and types of vegetation.
