Question

What are the factors affecting the variety of flora and fauna

Answer 1

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; the sandy soil is fit for cactus and thorny bushes, while the 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; along with their physical environment make the ecosystem. A very large ecosystem is called a biome. Biomes are identified on the basis of plants.

Answer 2

The factors that affect the various flora and fauna are
Temperature
Soil
Land
Climate
Sunlight
Precipitation or rainfall
Temperature-The character and extent of natural vegetation are mainly determined by the temperature of the region.
Soil-The type of soil varies from place to place. Different types of soil provides the basis for different types of vegetation.
Land-Land affect the natural vegetation of an region directly and indirectly.
Climate-Temperature, sunlight and rainfall determine the climate of a region or a place.
Sunlight-The variation in the duration of sunlight at different places is due to differences in latitude, altitude, season and duration of the day.
Precipitation-The thick or dense vegetation is determined by the amount of rainfall in a particular region.
