Ecoregions are areas defined by distinct ecological characteristics, including climate, soil, vegetation, and wildlife. They help scientists and conservationists understand the natural environment and manage resources effectively. Each ecoregion supports specific ecosystems and biodiversity, making them crucial for environmental studies. These regions are often classified into categories, such as terrestrial and aquatic ecoregions. For example, a temperate forest ecoregion may have different species and climate conditions compared to a desert ecoregion. Understanding ecoregions aids in conservation efforts and helps address environmental challenges like climate change and habitat loss.
