A biome is a specific environment that's home to living things suited for that place and climate. A desert biome is great for a lizard, but a koala needs the leafy greens of a forest biome.

A plant or animal makes its home in a specific biome, which is pronounced "BI-ohm." While a biome can range from an arctic tundra to a tropical rain forest, living things need to stay in the biome that's best suited to keeping them alive and growing. Scientists in the field of ecology, the study of the environmental connections between living things, work to understand the effects of climate change and population growth on biomes.
