    Read Explanation:

    • Biodiversity, short for biological diversity, encompasses the vast array of life on Earth at multiple levels.

    • It includes ecosystem diversity (the variety of habitats, biotic communities, and ecological processes), species diversity (the number and abundance of different species), and genetic diversity (the variation of genes within a species).

    • This rich tapestry of life is crucial for the stability and resilience of natural systems.
