The term for the variety and variability of life forms on Earth is termed biodiversity. This concept encompasses the diversity of species, genetic variability within populations, and the range of ecosystems. Biodiversity is crucial for maintaining ecosystem stability, resilience, and functions. Higher biodiversity ensures ecosystem services like pollination, water purification, and nutrient cycling. Conservation efforts aim to protect biodiversity due to its intrinsic value and importance to human well-being and environmental health.
