AP BIOLOGY

Detailed explanation-1: -The savanna biome is often described as an area of grassland with dispersed trees or clusters of trees. The lack of water makes the savanna a difficult place for tall plants such as trees to grow. Grasses and trees that grow in the savanna have adapted to life with little water and hot temperatures.

Detailed explanation-2: -Grassland (Savanna) The seasons in this biome are different than those of temperate grasslands. There are only two: the wet and the dry season. Fires are a common issue here due to lightning. All of these factors lead to grasses being the dominant plant life in the biome.

Detailed explanation-3: -A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses.

Detailed explanation-4: -Savanna is grassland with scattered individual trees. Savannas of one sort or another cover almost half the surface of Africa (about five million square miles, generally central Africa) and large areas of Australia, South America, and India.

Detailed explanation-5: -Savannas exist in areas where there is a 6-8 month wet summer season, and a 4-6 month dry winter season. The annual rainfall is from 10-30 inches (25-75 cm) per year. During the dry season, lightning often strikes the ground, igniting the dry grasses that cover the savanna.
