Biodiversity definition and types

The term “biodiversity” is derived from the combination of two words: “bio,” which means life, and “diversity,” which refers to the variety or differences. Therefore, etymologically, biodiversity can be understood as the “variety of life” or the “diversity of living organisms.” It encompasses the different species of plants, animals, microorganisms, and the ecosystems in which they exist. The concept highlights the richness, variability, and complexity of life forms on Earth, emphasizing the interconnectedness and interdependence of all living things.

Types of Biodiversity:

1. Genetic Diversity:
   • Genetic diversity refers to the variety of genes within a species. It includes differences in individual genes, as well as variations in gene combinations. This diversity is crucial for the adaptability and evolutionary potential of species.
2. Species Diversity:
   • Species diversity is the variety of different species within a particular ecosystem or on Earth as a whole. It includes the number of species present, their relative abundance, and the distribution of species.
3. Ecosystem Diversity:
