Biodiversity is a term used to describe the variety and abundance of living organisms within a particular ecosystem or on the planet as a whole. This includes the diversity of species, genetic diversity within species, and the variety of ecosystems and habitats in which organisms live. Research in biodiversity focuses on understanding and conserving this variety of life on Earth. Scientists study the distribution, abundance, and interactions of different species, as well as the factors that influence biodiversity such as climate change, habitat destruction, and pollution. Biodiversity research also plays a key role in identifying and protecting endangered species, managing ecosystems for sustainability, and developing strategies for preserving biodiversity in the face of increasing human impact on the planet.
