What is the African savanna ecosystem?
The African savanna ecosystem is a tropical grassland with warm temperatures year-round and with its highest seasonal rainfall in the summer. The savanna is characterized by grasses and small or dispersed trees that do not form a closed canopy, allowing sunlight to reach the ground.
What are 5 characteristics of a savanna?
Savanna vegetation includes scrub , grasses and occasional trees, which grow near water holes , seasonal rivers or aquifers . Plants and animals have to adapt to the long dry periods. Many plants are xerophytic – for example, the acacia tree with its small, waxy leaves and thorns.
Why is it called savanna?
The word savanna comes from a Panamanian word for prairie or plains. They are covered with tall grasses. They may have scattered bushes and trees, but not enough to keep grasses from growing. The most common definition of savanna is the tropical grassland, such as in Africa.

The Serengeti Plains are a grass savanna that has very dry but nutrient-rich volcanic sand.
What decomposers live in the African savanna?
Though some kinds of organisms are more abundant than others, bacteria, fungi, earthworms and insects all fill the decomposer role in savanna ecosystems.
What is savanna plants?
PLANTS: The savanna is dominated by grasses such as Rhodes grass, red oats grass, star grass, lemon grass, and some shrubs. Most savanna grass is coarse and grows in patches with interspersed areas of bare ground. You won’t see many trees in the savanna because of little rainfall.
Why is the savanna important to our ecosystem?
1) To protect and provide habitat for migratory birds – Savannas provide habitat for over 100 species of birds. 3) To support a natural diversity of plants and animals on refuge lands – Savannas support a wonderful variety of living things.
Is a savanna a terrestrial ecosystem?
Regions of similar climate and dominant plant types are called biomes. This chapter describes some of the major terrestrial biomes in the world; tropical forests, savannas, deserts, temperate grasslands, temperate deciduous forests, Mediterranean scrub, coniferous forests, and tundra (Figure 4).
What animals live in the savanna climate?

How did the Koppen Climate Classification system influence the savanna?
The Köppen climate classification system was strongly influenced by effects of temperature and precipitation upon tree growth, and his oversimplified assumptions resulted in a tropical savanna classification concept which resulted in it being considered as a “climatic climax” formation.
What is the vocabulary of the African savanna?

What is the difference between savanna and shrubland?
Savanna is grassland with scattered trees. Shrubland is dominated by woody or herbaceous shrubs. Large expanses of land in the tropics do not receive enough rainfall to support extensive tree cover. The tropical and subtropical grasslands, savannas, and shrublands are characterized by rainfall levels between 90–150 centimetres (35–59 in) per year.
