Detailed explanation-1: -The African savanna biome is a tropical grassland with warm temperatures all year and the most rainfall during the summer. The grasses and small or scattered trees that make up the savanna do not form a closed canopy, enabling sunlight to reach the ground.

Detailed explanation-2: -Savanna is a transitional type of climate found between the equatorial rainforests and hot deserts. savannas grow in tropical regions 8° to 20° from the Equator. Conditions are warm to hot in all seasons. Mean annual precipitation is generally 80 to 150 cm.

Detailed explanation-3: -The savannas are grasslands that have several months of dryness, followed by a rainy season. A majority of the soils in this area are Alfisols and Ultisols. These soils are very old and low in fertility, but since there is a dry season, more of the nutrients can stay in place.

Detailed explanation-4: -savanna, also spelled savannah, vegetation type that grows under hot, seasonally dry climatic conditions and is characterized by an open tree canopy (i.e., scattered trees) above a continuous tall grass understory (the vegetation layer between the forest canopy and the ground).

Detailed explanation-5: -The rainforest biome remains warm all year and must stay frost-free.
