A geographic region that contains distinct yet similar ecosystems and is defined by its specific climate, flora, and fauna is called a biome. Biomes are large ecological areas on the Earth’s surface, such as tundra, desert, tropical rainforest, or grassland, each supporting life forms adapted to its conditions. Unlike smaller ecosystems, biomes cover extensive regions and are shaped primarily by temperature, rainfall, and seasonal patterns, influencing the types of plants, animals, and ecological processes that can thrive there.
