The primary influences on plant distribution in different climates include temperature, precipitation, and soil composition. Regions with specific climatic conditions create favorable environments for certain plant species, influencing their growth, reproduction, and survival rates. For example, arid regions support specialized plants adapted to conserve moisture, while tropical climates host diverse, moisture-dependent species. Human activities, like deforestation and urbanization, also affect plant distribution by altering habitats. Understanding these influences is crucial for conservation efforts and effective management of global biodiversity amid changing climates.
