The primary factor that influences species distribution is the combination of abiotic factors, such as climate, soil type, and water availability, along with biotic interactions like competition and predation. Each species has specific habitat requirements and tolerance limits, impacting where they can thrive. Environmental conditions, including temperature and precipitation, dictate resource availability and habitat suitability. Additionally, human activities, such as urbanization and agriculture, can disrupt natural habitats, further influencing species distribution. Understanding these factors is essential for conservation efforts and predicting how species may respond to changing environments.
