The correct answer is Savannah.

Key Points

  • Savannah 
  • Tropical grasslands, known as savannas, are found in warm climates with distinct wet and dry seasons.
  • They are characterized by scattered trees and a mix of grasses, supporting diverse wildlife like lions, elephants, and zebras.
  • Major savanna regions include Africa (Serengeti), South America (Cerrado), and northern Australia.
  • These ecosystems are crucial for grazing animals and are often affected by seasonal fires.

Additional Information

  •  Taiga
    • Taiga is not a grassland but the world's largest terrestrial biome.
    • Also called boreal forest, it consists of dense coniferous forests in cold subarctic regions.
    • Found in Canada, Russia, and Scandinavia, it has long winters and short summers.
    • Dominant trees include spruce, pine, and fir, adapted to snowy conditions.
    • Wildlife includes moose, wolves, and bears, unlike the open grasslands of savannas.
  • Pampas
    • Pampas are temperate grasslands, not tropical.
    • Located in South America (Argentina, Uruguay, Brazil), they have fertile soils ideal for agriculture.
    • These grasslands experience moderate rainfall and no extreme temperatures.
    • Historically home to gauchos (cowboys) and grazing animals like wild horses.
    • Unlike savannas, they lack scattered trees and have a more uniform grassy landscape.
  • Prairie
    • Prairie is another temperate grassland ecosystem.
    • Found in North America (especially the U.S. Midwest and Canada), it has hot summers and cold winters.
    • Divided into tallgrass, mixed-grass, and shortgrass prairies based on rainfall.
    • Once roamed by bison, now largely converted to farmland (wheat, corn).
    • Unlike tropical savannas, prairies have fewer trees and distinct seasonal temperature variations
