Biodiversity is the rich variety of life on Earth
bio means life, diversity means variety. It's the difference in the genes that makes the difference!
There are 3 kinds of biodiversity
  • Variety of genes
    Poodles, beagles, and rottweilers are all dogs—but they're not the same because their genes are different. It's the difference in our genes that makes us all different.
  • Variety among species
    Scientists group living things into distinct kinds of species. For example, dogs, dragonflies, and daisies are all different species.
  • Variety of ecosystems
    Coral reefs, wetlands, and tropical rain forests are all ecosystems. Each one is different, with its own unique species living in it. Genes, species, and ecosystems working together make up our planet's biodiversity.
