A tree savanna at Tarangire National Park in Tanzania in East Africa A grass savanna at Kruger National Park in South Africa. A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) biome and ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close.
Tropical and subtropical grasslands, savannas, and shrublands is a terrestrial biome defined by the World Wide Fund for Nature. [1] The biome is dominated by grass and/or shrubs located in semi-arid to semi- humid climate regions of subtropical and tropical latitudes .
The linkages in a food web illustrate the feeding pathways, such as where heterotrophs obtain organic matter by feeding on autotrophs and other heterotrophs. The food web is a simplified illustration of the various methods of feeding that link an ecosystem into a unified system of exchange.
Temperate savannahs, found in Southern South America, parts of West Asia, South Africa and southern Australia, and parts of the United States, are a mixed grassy woodland ecosystem defined by trees being reasonably widely spaced so that the canopy does not close, much like subtropical and tropical savannahs, albeit lacking a year-round warm ...

The Cerrado biome is strategic for the water resources of Brazil. The biome contains the headwaters and the largest portion of South American watersheds (the Paraná-Paraguay, Araguaia-Tocantins, and São Francisco river basins) and the upper catchments of large Amazon tributaries, such as the Xingu and Tapajós. During the last four decades ...
Woodlands with a grassy understorey, savanna, and grasslands are the predominant vegetation types. Pockets of dense lancewood-bullwaddy woodland with a sparse understorey are found in the eastern portion of the ecoregion. Plant communities vary with soils and rainfall.
