A habitat is the natural environment where an organism lives, providing essential resources such as food, shelter, and water. It encompasses all living (biotic) and non-living (abiotic) elements that influence the survival and reproduction of species. Different habitats support diverse ecosystems, including forests, deserts, and aquatic systems, which are characterized by unique climatic and geological features, helping to sustain the biodiversity necessary for ecological stability. Preserving habitats is crucial for maintaining healthy populations of species and overall ecosystem function.
