The geographical term for a region characterized by diverse climates and ecosystems is a biome. Biomes are large ecological areas on the earth's surface that share similar climate conditions, plants, and wildlife. They include various types, such as tropical rainforests, deserts, and temperate forests. Biomes help scientists categorize and study the distribution of life on Earth. Understanding these regions is crucial for conservation efforts, as they are often affected by climate change and human activities. Each biome supports distinct biological communities, contributing to the planet's overall biodiversity.
