    • BY ABRIL AGNESE AND VALENTINA BASSO TROPICAL GRASSLANDS
    • Tropical Grasslands  Flat open plains in the central part of continents. They occur between 5° and 15° north and south the Equator. They own its name from the grasses that compose the majority of the vegetation.
    • DRY SEASON RAINY SEASON TWO SEASONS
    • Dry and Rainy  The rainy season in an area occurs when the sun is directly overhead and the trade winds meet there. As the warm moist air is forced to rise, it rains heavily.  When the sun is no longer directly overhead, the point where the trade winds meet shifts and the dry season begins. The trade winds are dry because they have already shed any moisture on the coast.
    • Vegetation Only a few trees grow in the tropical grasslands, the most common is the acaica. However, there are around 8,000 species of grasses well adaptepd to surviving the dry season. Their long root reaches out in search of the little water that’s available.
    • GRASSLAND ANIMALS  Most of them are herbivores.  Others are hunting animals, such us lions and cheetahs.  Many animals live in large groups  Some of the fastest animals such as cheetahs, wallabies and ostriches live in the grasslands.  Speed is really important for survival for the hunter and the hunted.
    • THE TSETSE FLY Many grassland areas are now used for farming. However there’s a big part which is almost untouched because of a parasite carried by an insect called the tsetse fly, this insect infects humans and animals.
