The term for a large area of land with similar climate and vegetation is called a biome. Biomes encompass various ecosystems that share common environmental conditions, plant types, and animal species. They can include regions such as tropical rainforests, deserts, grasslands, and tundras. Each biome presents distinct characteristics tailored to the climate, such as temperature ranges and precipitation levels, influencing the biodiversity found within it. Understanding biomes is crucial for the study of ecology and conservation, as they provide insight into the interactions between organisms and their environments and how climates shape ecosystems.
