Science
Biomes.
Definition
Biomes are large geographic regions classified by their dominant climate, vegetation, and animal life. Temperature and precipitation are the primary factors that determine which biome exists in a given area.
Examples
Real-world.
- 1 The tundra biome has permafrost, low temperatures, and minimal vegetation such as mosses and lichens
- 2 Tropical rainforests receive over 200 cm of rain per year and have the highest biodiversity of any terrestrial biome
- 3 Grasslands (savannas and prairies) are dominated by grasses and have seasonal rainfall patterns that prevent large-scale tree growth
Key Fact
Major terrestrial biomes: tundra, taiga, temperate forest, tropical rainforest, grassland, desert, chaparral.
