Define biodiversity.

Biodiversity refers to the variety of living organisms within a particular habitat or ecosystem. This definition encompasses not only the number of different species present but also the richness and abundance of those species, as well as the complexity of their interactions with each other and their environment. In essence, biodiversity is a holistic concept that captures the variety of life forms, including plants, animals, fungi, and microorganisms, and emphasizes their roles and relationships within ecosystems.

By understanding biodiversity in this broader context, it helps underscore the importance of conserving ecosystems, as high levels of biodiversity contribute to ecosystem resilience, productivity, and the overall health of the planet. Thus, defining biodiversity strictly as just the number of species overlooks the critical aspect of their interactions and various contributions to ecological stability and function.
