What are the four levels of biodiversity?

The four levels of biodiversity include genetic diversity, species diversity, ecosystem diversity, and functional diversity. Genetic diversity refers to variations in genes within a species, enabling adaptation and survival under changing environmental conditions. Species diversity represents the variety and relative abundance of different species within a specific habitat or region. Ecosystem diversity involves the diversity of habitats, biological communities, and ecological processes across different geographical areas. Functional diversity refers to the range of biological roles or functions performed by organisms within an ecosystem, such as pollination, decomposition, and nutrient cycling, which are essential for maintaining ecosystem stability and productivity.
