1. Climate: Climate plays a major role in determining the distribution of terrestrial biomes. Factors such as temperature, precipitation, humidity, and sunlight affect the types of plants and animals that can thrive in a particular region. For example, tropical rainforests are found in regions with high temperatures and abundant rainfall, while deserts are found in regions with low precipitation.
2. Soil: Soil characteristics, such as texture, pH, and nutrient content, influence the types of plants that can grow in a particular area. For example, acidic soils may support different plant communities than alkaline soils.
3. Topography: The physical features of an area, such as elevation, slope, and aspect, can affect the distribution of terrestrial biomes. For example, mountains may have different climate zones at different elevations, and slopes that face the sun may be warmer and drier than those that face away from the sun.
4. Biotic interactions: The presence or absence of certain species can also influence the distribution of terrestrial biomes. For example, the presence of large herbivores can prevent the establishment of forests, while the presence of certain plant species can create microclimates that support other species.
5. Disturbance: Natural disturbances, such as fires, floods, and volcanic eruptions, can also affect the distribution of terrestrial biomes. These disturbances can create new habitats or destroy existing ones, leading to changes in the composition of plant and animal communities.
