Plant distribution refers to the way different plant species are spread across various regions of the world. This distribution is influenced by factors such as climate, soil type, and topography. For example, tropical rainforests are home to a diverse range of plant species due to their warm temperatures and high rainfall, while deserts have fewer species adapted to dry conditions. Additionally, human activities, such as agriculture and urban development, can impact plant distribution. Invasive species may also alter the natural balance, leading to changes in local ecosystems. Understanding plant distribution helps in conservation efforts and managing biodiversity effectively.
