The term for the variety of life forms within a given ecosystem is known as biodiversity. Biodiversity encompasses the range of species, genetic variation, and ecosystems present in a particular area. It plays a crucial role in maintaining ecological balance, resilience, and productivity. High biodiversity contributes to stable ecosystems, providing essential services such as pollination, nutrient cycling, and climate regulation. Protecting biodiversity is vital for sustaining life on Earth and ensuring the health of future generations.
