| ||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.

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.
