A biome is a large geographical area characterized by specific climate conditions and the plant and animal communities adapted to them. Key components include: Climate: Temperature and precipitation patterns are the primary determinants of a biome. Vegetation: The dominant plant life (e.g., trees, grasses, shrubs) shapes the biome. Fauna: Animal life is adapted to the vegetation and climate. Major terrestrial biomes include: Tropical Rainforests: High temperature, high rainfall, high biodiversity. Savannas: Grasslands with scattered trees, distinct wet and dry seasons. Deserts: Very low rainfall, extreme temperatures (hot or cold). Temperate Grasslands: Moderate rainfall, distinct seasons, dominated by grasses. Temperate Deciduous Forests: Moderate temperature and rainfall, trees lose leaves seasonally. Boreal Forests (Taiga): Cold temperatures, coniferous trees, long winters. Tundra: Extremely cold, low precipitation, permafrost, low-growing vegetation. Aquatic biomes include freshwater (lakes, rivers) and marine (oceans, coral reefs) environments.
