Final answer:
Grasslands with scattered trees are the predominant vegetation in the Savannah region of sub-Saharan Africa, with grasses and forbs having adapted well-established root systems to thrive in this biome characterized by a dry season and frequent fires.
Step-by-step explanation:
The dominant type of vegetation in the Savannah region of sub-Saharan Africa is grassland with scattered trees. These expansive grasslands are an iconic feature of Africa, covering almost half of the continent's surface area. The savanna biome is characterized by high temperatures averaging from 24°C to 29°C (75°F to 84°F) and a significant range of annual rainfall spanning from 10-40 cm (3.9-15.7 in)
The biome experiences an extensive dry season, during which fires are common, shaping the ecology of the area. Plants in the savanna, especially grasses and forbs, have adapted to the environment by developing well-established root systems that allow quick regeneration post-fire. These root systems help to maintain the dominance of grasses in the savanna landscape, limiting the presence of trees.
The Savannah region of sub-Saharan Africa is dominated by grasses. The savanna is a grassy plain, covering almost half the surface of the continent. It stretches from the warm and humid rainforest to the torrid zone of the Sahara, and encompasses snow-capped mountains, vast grassy plains dotted with trees, and marshy tropical areas.
