Different types of biodiversity include genetic diversity, species diversity, and ecosystem diversity. Genetic diversity refers to the variety of genes within a species, providing the raw material for evolution and adaptation. Species diversity encompasses the number of different species within a given area, playing a key role in ecosystem resilience and stability. Ecosystem diversity refers to the different types of habitats, communities, and ecological processes that occur in a specific region. Preserving these various forms of biodiversity is essential for maintaining healthy ecosystems, supporting food security, and ensuring overall environmental sustainability.
