The scientific term for the variety of life in a particular habitat is biodiversity. This concept encompasses the diversity of species, genetic variability within species, and the variety of ecosystems present in a given area. High biodiversity typically indicates a healthy, functioning ecosystem, where various species and interactions contribute to stability and resilience. Biodiversity is crucial for ecosystem services such as pollination, nutrient cycling, and climate regulation. Conservation efforts often focus on preserving biodiversity to maintain ecological balance and support the survival of both natural habitats and human societies.
